Abstract:
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.

Claim (Index 1):
A method for forming a graphene-reinforced polymer matrix composite, comprising:\n (a) distributing graphite microparticles into a molten thermoplastic polymer phase, wherein at least 50% by weight of the graphite in the graphite microparticles consists of multilayer graphite crystals between 1.0 and 1000 microns thick along a c-axis direction; and (b) applying a succession of shear strain events to the molten polymer phase so that the shear stress within said molten polymer phase is equal to or greater than the Interlayer Shear Strength (ISS) of said graphite microparticles and said molten polymer phase exfoliates the graphite successively with each event until said graphite is at least partially exfoliated to form a distribution in the molten polymer phase of essentially pure and uncontaminated single- and multi-layer graphene nanoparticles less than 10 nanometers thick along the c-axis direction;
