Abstract
Electrically conductive ultrahigh molecular weight polyethylene (UHMWPE)/graphene nanosheets composites with a segregated structure were prepared by electrostatic adsorption method. It was found that UHMWPE powders could generate static electricity after high-speed mechanical friction which was beneficial to adsorb fluffy graphene on the surface of polymer powders. UHMWPE/graphene nanosheets composites with a segregated network produced by hot-pressing exhibited a dramatic enhancement in electrical conductivity with the percolation threshold of 0.1 vol.%.
