NOVELTY - Preparation of doped graphene conductive polypropylene fiber involves mixing 10-15 pts. wt. graphene oxide, 2-8 pts. wt. polyoxyethylene castor oil, 1-4 pts. wt. tetrabutyl titanate, 2-6 pts. wt. polydimethylsiloxane, 3-7 pts. wt. polypropylamine and 4-12 pts. wt. polyethylene, extruding, melting, granulating, mixing 20-30 pts. wt. granules, 1-4 pts. wt. resorcinol-formaldehyde epoxy resin, 2-6 pts. wt. ammonium persulfate butoxyethyl ester, 3-5 pts. wt. 2-butyoxyethanol ethyl acetate, 2-7 pts. wt. silica fume and 1-6 pts. wt. polylactic acid, melt spinning, cooling, molding, and stretching. USE - Method for preparing doped graphene conductive polypropylene fiber (claimed). ADVANTAGE - The fiber has 4-10 S/cm electrical conductivity, 4 cN/dtex breaking strength and 10% improved elongation.
