PTFE. The solvent is selected from ethanol or acetone. USE - Graphene composite polyethylene terephthalate fiber (claimed). ADVANTAGE - The graphene composite polyethylene terephthalate fiber has excellent comprehensive performance. DETAILED DESCRIPTION - Graphene composite polyethylene terephthalate fiber comprises 10-25 pts. wt. composite masterbatch, 70-90 pts. wt. polyethylene terephthalate, 30-40 pts. wt. solvent and 2-5 pts. wt. surfactant. The composite masterbatch comprises 10-29 pts. wt. graphene, 5-10 pts. wt. aniline monomer, 5-10 pts. wt. caffeic acid, 1-3 pts. wt. silane coupling agent, 15-30 pts. wt. filler, 1-2 pts. wt. microcrystalline cellulose, 1-3 pts. wt. oxidizing agent, 10-30 pts. wt. solvent and 1-3 pts. wt. PTFE. The filler is selected from silica, aluminum oxide, aluminum powder, titanium dioxide or pyrophyllite. The oxidizing agent is selected from potassium permanganate, hydrogen peroxide or peracetic acid. The solvent is selected from ethanol or acetone. The graphene is 3-10 layers of graphene. An INDEPENDENT CLAIM is included for preparation of graphene composite polyethylene terephthalate fiber.
