▎ 摘　　要

NOVELTY - Preparing a polyimide-graphene/polyimide-carbon compound composite material, involves: modifying graphene/carbon compound by covalently bonding an amine-substituted aromatic/aliphatic compound on the surface of the graphene/carbon compound; performing polymerization by adding the modified graphene/carbon compound to a polyimide precursor; and heat-treating the prepared polyimide precursor-graphene/polyimide precursor-carbon compound composite to prepare a polyimide-graphene/polyimide precursor-carbon compound composite materials. The carbon compound comprises carbon nanotube and clay. USE - The method is useful for preparing a polyimide-graphene/polyimide-carbon compound composite material (claimed), which is useful in electric and electronic industries. ADVANTAGE - The method provides the polyimide graphene with improved mechanical strength and electrical conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the polyimide-graphene composite material prepared by the method.
