Abstract

The invention discloses an antioxidant polypyrrole conducting material which is prepared from the following raw material in parts by weight: 0.7 to 1 part of 2-thiol benzimidazole, 140 to 200 parts ofantioxidant modified pyrrole monomer, 5 to 7 parts of initiator, 0.1 to 0.3 part of bisphenol a diglycidyl ether, 3 to 4 parts of polyamide wax micropowder, 10 to 13 parts of graphene and 1 to 2 parts of zinc cyanurate. According to the antioxidant polypyrrole conducting material disclosed by the invention, the 2-benzimidazolethiol is utilized as the raw material to prepare an amide solution, andthen the amide solution is utilized to disperse the graphene; thus, the surface reaction activity of the graphene is improved; then the graphene participate in polymerization reaction of the antioxidant monomer, so that a composite material with strong oxidation resistance and high mechanical stability is achieved.
