▎ 摘 要
NOVELTY - Preparing graphene-polyimide composite resin comprises (i) performing polymerizing reaction of graphene powder, dianhydride and diamine in the non-polar solvent to obtain the prepolymer suspension, suction-filtering prepolymer suspension and drying into powder to obtain the graphene-polyimide resin precursor powder; and (ii) hot press molding graphene-polyimide resin precursor powder. USE - The method is useful for preparing graphene-polyimide composite resin is useful as an engineering material, and macromolecular resin. ADVANTAGE - The method prepares graphene-polyimide composite resin with low shrinkage, few defects, good mechanical performance by directly forming complex shape and thick wall product and uniform and high content graphene with convenient the whole synthesis process, rapid forming speed and low shrinkage and less defect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene-polyimide composite resin, prepared as mentioned above.
