Abstract
There is still lack of information regarding changes in the microstructure of polycarbonate (PC) due to the addition of secondary phases and processing. In this work, PC composites with graphene were expanded using supercritical CO2 (sc-CO2). Raman spectroscopy, XRD and DSC demonstrated that the presence of graphene and CO2 induced PC’s crystallization during saturation. Double melting behavior indicated the presence of crystals with different thermal stabilities. Saturation temperature, time...
