Abstract

See full text

The present invention discloses a graphene composite material and a preparation method thereof. By adding pleated graphene oxide microspheres and a catalyst to a precursor, the pleated graphene oxide microspheres are allowed to be highly dispersed and gradually disassociated into single-layer graphene oxide sheets during the process of polycondensation, the partially esterified molecules react with the hydroxyl and carboxyl group on the surface of graphene oxide sheets to form a chemical bond, and the graphene oxide is thermally reduced, to finally obtain a composite material comprising PET and graphene sheets having PET grated to the surface.
