Patent ID: 7799850

Claim:
A method for preparing an epoxy composite material containing polyaniline/carbon black composites comprising the steps of: adding aniline into nanoscale carbon black solution and then adding ammonium persulfate and acid into the mixture to produce the polyaniline/carbon black composites with a core-shell structure; adding a plurality of polyaniline/carbon black composites with core-shell structure into an epoxy resin; and distributing the plurality of polyaniline/carbon black composites with core-shell structure in the epoxy resin to produce the epoxy composite material containing polyaniline/carbon black composites, said polyaniline/carbon black composites with core-shell structure containing 20-30 wt. % of nanoscale carbon black and the weight ratio of said polyaniline/carbon black composites with core-shell structure to the epoxy resin is 3:7.
