Resum
The viscoelastic properties of polycarbonate (PC) nanocomposite foams containing graphene nanoplatelets (GnP), prepared by one and two-step supercritical CO2 dissolution, were characterized by dynamic-mechanical-thermal analysis. Three factors were detected to influence the mechanical performance of foams: relative density, the eventual presence of a PC crystalline phase and GnP's amount. Relative density was found to be the most important one, with the storage modulus following a power-law beha...
