A method for forming a graphene-reinforced polymer matrix composite is disclosed. The method includes distributing graphite microparticles into a molten thermoplastic polymer phase; and applying a succession of shear strain events to the molten polymer phase so that the molten polymer phase exfoliates the graphite successively with each event until at least 50% of the graphite is exfoliated to form a distribution in the molten polymer phase of single- and multi-layer graphene nanoparticles less than 50 nanometers thick along the c-axis direction.
A graphene-reinforced polymer matrix composite, comprising a distribution of mechanically exfoliated single- or multi-layer graphene nanoparticles in a thermoplastic polymer matrix, wherein the composite comprises contamination-free graphene-polymer interfaces, and wherein the polymer adheres to or is covalently bonded to the graphene-polymer interfaces.
