    La particular estructura química de la matriz perfluorosulfónica del Nafion, con dominios hidrofílicos e hidrofóbicos segregados formando canales nanoscópicos, ha dado pie a su uso como modelo de estructura para la fabricación de nanocompuestos polímero-metal mediante el crecimiento de nanopartículas metálicas en su interior. En particular, mediante la técnica de síntesis intermatrical se ha conseguido el crecimiento de nanopartículas de plata (de un tamaño medio próximo a los 10 nm), las cuales presentan una distribución particular en forma de líneas casi paralelas, que difiere de la distribución más habitual de mayor concentración en la superficie. Para evaluar posibles aplicaciones de este nuevo material se ha realizado su caracterización mediante diferentes técnicas: microscop1ca, análisis químico superficial, mecánica, eléctrica/electroquímica. Los resultados obtenidos muestran que la presencia de nanopartículas no parece afectar significativamente al transporte de protones en la membrana, pero sí modifican la superficie de la misma. Además, la resistencia mecánica del nuevo material es inferior a la del Nafion no modificado debido a la interacción de las partículas con las cadenas de polímero. También se ha observado que algunas de estas propiedades varían de forma importante en/unción del grado de hidratación de la muestra. The particular chemical structure of Nafion, a perfluorosulfonic matrix with segregated hydrophilic and hydrophobic domains forming nanoscale channels, has led to its use as a model structure for the manufacture of polymer-metal nanocomposites by growing in it metal nanoparticles. in particular, using the technique of intermatrix synthesis, the growth of silver nanoparticles (with an average diameter close to 10 nm) has been achieved Moreover, samples exhibit a particular distribution of such nanoparticles in the form of nearly para/le/ fines, what differs from the usual major distribution on the membrane surface. To evaluate the potential application of this new material in electrochemical applications, we proceeded to their characterization by different techniques: microscopic, surface chemical analysis, mechanical and electrical/electrochemical. These results show that the presence of nanoparticles does not seem to significantly affect the transport of protons in the membrane bulk, but it modifies its surface. Furthermore, the mechanical strength of the new material is lower than the unmodified Nafion due to the high interaction between nanoparticles and polymer chains. Moreover, it was a/so observed that some of the mentioned properties significantly varied depending on the degree of hydration of the sample

    The development of suitable biomimetic scaffolds is a fundamental requirement of tissue engineering. Although electrospinning has emerged as an effective method for producing such scaffolds of nanometer-sized fibers, the influence of solution characteristics on the morphology of the resulting nanofibers depends on each polymer solution system. In this study, gelatin nanofibers and microfibers were prepared via electrospinning using mixtures of water and acetic acid at different ratios as solvents. The viscosities of gelatin solutions before electrospinning were analyzed and two different behaviors were found as a function of the solvent composition, taking into account classic models of polymer science. A power law relationship between viscosity and gelatin concentration was found for each solvent system, and an empirical model including the influence of acetic acid was obtained for aqueous systems. Moreover, a ternary diagram considering gelatin, water, and acetic acid mass fractions was constructed as a tool to establish the electrospinnability domains in terms of fiber occurrence and morphology. Also, the isodiametric curves were defined in the fibers region. Finally, in order to correlate the diameter of electrospun nanofibers and the electrospinnability zones, the Berry number was used. However, as its only allows the range of electrospinnability to be established for a fixed solvent composition, a new dimensionless parameter (Bemod) was suggested to take into account all the acetic acid aqueous solutions as a single solvent

    This work reports the results obtained by the development of two types of nanocomposite membranes containing metal nanoparticles prepared by applying the Intermatrix Synthesis technique for the synthesis of silver nanoparticles in the ion-exchange matrices of sulfonated polyethersulfone-Cardo and Nafion membranes. The stability (in terms of silver nanoparticles loss) of the polymer-metal nanocomposites was evaluated by using both ultrasonic and thermostatic baths and appeared to be appropriate for their practical applications. The dual-function nanocomposites were characterized in batch tests, first, by monitoring their catalytic activity in the reduction of p-nitrophenol to p-aminophenol and second, by evaluating their antibacterial efficiency towards E. coli. The results of the catalytic tests have shown that polymer-silver nanocomposites demonstrate remarkably better activity in comparison with their polymer-palladium nanocomposite analogues. The same nanocomposites have been shown to permit the complete disinfection of E. coli containing water within a short period of time.

    Nafion has been frequently used for the synthesis of nanoparticles by taking advantage of its so-called cluster-network structure. Unexpectedly, the synthesis of AgNPs inside Nafion 117 was found to produce NPs organization, resulting in a regular pattern that could reveal the real morphology of the polymer.

    Plastic composites are made of polymers and different reinforcements that originally were synthetic and non-biodegradable. Since 1990’s, many biodegradable composites, formed by a biodegradable matrix and natural fibers, have been proposed. In spite of the advantages of biocomposites, it is important to ponder the technical drawbacks of these natural fibers, mainly from a vegetable origin, and their environmental impacts (EIs). Vegetable fibers imply a land use that can compete with food production. Chicken feathers (CFs), made of keratin fibers, are a potential alternative as they are a waste material, produced in large quantities (800,000 ton/year in EU-27), do not compete with human food production and have been scarcely used up to now. Taking on board these premises, a biocomposite made of PLA and CFs was fabricated at lab-scale as new material. However, before using CFs as reinforcement, sanitizing pretreatments have been envisaged before, due to their quick decay. The EIs of these treatments were experimentally quantified and a cradle-to-gate Life Cycle Assessment (LCA) was performed to evaluate altogether the impacts of manufacturing a technical panel with different content of CFs (up to 35% v/v). As main results, the avoided burdens of the CF waste treatment and the energy consumption for the drying step must be optimized to achieve lower EIs for the preparation of CFs/PLA composites

    Over the last years, the demand of textile products with enhanced functionalities, such as antibacterial, antistatic, stain resistant, or UV protective has grown considerably. These materials must satisfy not only the final costumer needs, yet the manufacturer economic aspects, but also the growing ecological concerns. In this sense, intensive development of Nanotechnology in the field of the nano-structures generation has contributed with a new interesting insight. With the application of the nanotechnology to textile fibers, new products with totally new or far improved functions with protective properties for humans and the environment can be easily obtained, without modifying the intrinsic textile properties. In this work we present the Inter-Matrix Synthesis (IMS) of silver nanoparticles (AgNPs) in different polymeric textile fibers such as polyacrylonitrile and polyamide fibers.

    Cation exchange polymeric matrices are widely used in water treatment protocols to reduce the mineral content of hard waters, even for human consumption. However, they are not antibacterial and flowing bacteria can be trapped in their structures and proliferate, thus acting as microbial contamination sources. Here, Ag@Co-nanoparticles (Ag@Co-NPs) with a low-cost superparamagnetic Co0-core and an antibacterial Ag-shell are synthesized on granulated cation exchange polymeric matrices under soft reaction conditions. The presence of these NPs provides the final nanocomposite (NC) with additional functionalities (superparamagnetism and antibacterial activity) making it ideal for water purification applications. Ag@Co-NPs are synthesized in situ on four cation exchange polymeric matrices containing either strong (sulfonic) or weak (carboxylic) acid functional groups homogeneously distributed (C-type) or concentrated on an external shell (SST-type) by the intermatrix synthesis (IMS) method. The NCs are characterized (metal content, NP size and distribution, metal oxidative state, and metal release) and evaluated for water purification applications.

    In this paper, we report the intermatrix synthesis of Ag nanoparticles in different polymeric matrices such as polyurethane foams and polyacrylonitrile or polyamide fibers. To apply this technique, the polymer must bear functional groups able to bind and retain the nanoparticle ion precursors while ions should diffuse through the matrix. Taking into account the nature of some of the chosen matrices, it was essential to try to activate the support material to obtain an acceptable value of ion exchange capacity. To evaluate the catalytic activity of the developed nanocomposites, a model catalytic reaction was carried out in batch experiments: the reduction of pnitrophenol by sodium borohydride

    Chicken feathers (CFs), mainly discarded nowadays, are an alternative reinforcement to be applied in the preparation of composite materials (CMs). The effect of different sanitizing methods on the properties of both CFs and the corresponding CMs has been studied. Some characteristic parameters such as density have been found to be dependent on the treatment that CFs endure, whereas the mechanical properties of the CMs made of thermoplastics matrices (e.g. polypropylene and high density polyethylene) were only slightly affected by the treatment. The introduction of CFs decreased the tensile strength of the CMs compared with the neat polymers while other parameters (e.g. Young’s modulus) were essentially unaffected

    Chicken feathers (CFs) are a waste material generated from poultry industry in large quantities. A composite material constituted of poly lactide and CFs is proposed in order to prepare a biodegradable composite with low environmental impact. In order to evaluate its environmental impact, a Life Cycle Assessment (LCA) is performed. The results show that, from the environmental point of view, the more chicken feathers in the material, the greater is its impact. This is mainly due to the non - inclusion of the impact data regarding CFs current waste management treatments required in accordance with the European Directive CE 1069/2009 (in study) and to the high energy consumption of the pre - treatment stages (cleaning and sanitizing) required to transform CFs waste into a CFs technical material that can be used for the preparation of CFs/PLA composites material, which needs to be optimized.

    This manuscript describes the synthesis (based on the intermatrix synthesis (IMS) method), optimization, and application to bacterial disinfection of Ag@Co polymer metal nanocomposite materials with magnetic and bactericidal properties. This material showed ideal bactericide features for being applied to bacterial disinfection of water, particularly (1) an enhanced bactericidal activity (when compared with other nanocomposites only containing Ag or Co nanoparticles), with a cell viability close to 0% for bacterial suspensions with an initial concentration below 105 colony forming units per milliliter (CFU/mL) after a single pass through the material, (2) capacity of killing a wide range of bacterial types (from coliforms to Grampositive bacteria), and (3) a long performance-time, with an efficiency of 100% (0% viability) up to 1 h of operation and higher than 90% during the first 24 h of continuous operation. The nanocomposite also showed a good performance when applied to water samples from natural sources with more complex matrices with efficiencies always higher than 80%.

    En raison de leurs grandes surfaces spécifiques les nanoparticules métalliques (N PM) possèdent des propriétés physico-chimiques uniques par rapport à la forme macroscopique du même matériau, en particulier en matière de réactivité catalytique. Afin de conserver ces spécificités, il est important de maitriser leur stabilité en évitant leur agrégation. La synthèse in situ, dite inter-matricielle, de NPM au sein d’une matrice polymère permet de les stabiliser sans perte de réactivité tout en conservant leurs propriétés catalytiques élevées. En utilisant cette stratégie de synthèse, nous avons développé des réacteurs membranaires catalytiques (RM C) contenant des NPM permettant ainsi de réaliser une réaction et une séparation lors d'un seul et même procédé. Les performances catalytiques des membranes ainsi obtenues ont été évaluées sur la réaction modèle de réduction du p-nitrophénol en 4-aminophénol par du borohydrure de sodium. Les membranes chargées en NPM de Palladium ont été testées en filtration frontale et ont montré une dégradation complète possible du p-nitrophénol. Metal Nanoparticles (MNPs) have unique phyico-chemical properties advantageous for catalytic applications which differ from bulk material. However, the main drawback of MNPs is their insufficient stability due to a high trend for aggregation. To cope with this inconvenience, the stabilization of MNPs in polymeric matrices has been tested. This procedure is a promising strategy to maintain catalytic properties. The aim of this work is the synthesis of polymer-stabilized MNPs inside functionalized polymeric membranes in order to build catalytic membrane reactors. First, the polymeric support must have functional groups capable to retain nanoparticle precursors (i.e. sulfonic). Then, nanoparticles can grow inside the polymeric matrix by chemical reduction of metal ions. The catalytic performance of developed hollow fibers has been evaluated by using the reduction of nitrophenol to aminophenol by sodium borohydride. Hollow fiber modules with Pd MNPs have been tested in dead-end and cross-flow filtration. Complete nitrophenol degradation is possible depending on operation parameters
