▎ 摘　　要

NOVELTY - The method involves distributing graphite microparticles into a molten thermoplastic polymer phase comprising molten thermoplastic polymer. Succession of shear strain events are applied to the molten polymer phase such that the molten polymer phase exfoliates the graphene successively with each event until tearing of exfoliated multilayer graphene sheets occurs and produces reactive edges on the multilayer sheets that react with and cross-link the thermoplastic polymers, where thermoplastic polymers are subjected to UV degradation. USE - Method for forming a high-strength graphene-reinforced polymer matrix composite for an automotive, aircraft or aerospace part (claimed) for a commercial application. Can also be used for a boat hull, transportation vehicle lightweight armor i.e. vehicular or personnel armor, pressure vessel, reactor chamber, polymer powder for 3-D printing, spray coating, transparent electrode for electronic device touch screens, solar panel and flat-panel display and for static-discharge control in hospitals. ADVANTAGE - The method enables reducing millimeter-sized particles to micron-sized dimensions using ball milling and attritor milling in an efficient manner. The method enables reducing turbocharger lag due to resulting weight reduction. The method enables producing polymer matrix composite that includes increased specific stiffness and strength, enhanced electrical/thermal conductivity and retention of optical transparency in a cost-effective manner. The method enables a surface chemistry or nanostructure of the dispersed graphite to be modified to enhance bond strength with the polymer matrix. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a high-strength graphene-reinforced polymer matrix composite (2) a thermoplastic polymer composite (3) an automotive aircraft or aerospace part (4) a graphene cross-linked polymer particles (5) a polymer composition. DESCRIPTION OF DRAWING(S) - The drawing shows a photograph of morphology analysis of 2% graphite exfoliated in polysulfone at mixing times of 3 minutes, 30 minutes and 90 minutes.
