Abstract

A method for forming a graphene-reinforced-polymer matrix composite by distributing graphite microparticles into a molten thermoplastic polymer phase comprising one or more molten thermoplastic polymers; and applying a succession of shear strain events to the molten polymer phase so that the molten polymer phase exfoliates the graphene successively with each event, until tearing of exfoliated multilayer graphene sheets occurs arid produces reactive edges on the multilayer sheets that react with and cross-link the one or more thermoplastic polymers; where the one or more thermoplastic polymers are selected from thermoplastic polymers subject to UV degradation.
