▎ 摘　　要

NOVELTY - Graphene-crosslinked carbon fiber tow, is claimed. The carbon fibers in the tow are cross-linked by graphene sheets distributed in the axial direction of the fibers. The surface of the carbon fiber and the graphene sheet are connected by van der Waals force and hydrogen bonding. USE - Used as graphene-crosslinked carbon fiber tow. ADVANTAGE - The fiber tow has high crosslinking strength, good mechanical property and conductivity and is environment-friendly. The method is simple. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the (1) preparing the graphene-crosslinked carbon fiber tow, comprising (i) removing a sizing agent on the surface of the carbon fiber, oxidizing and modifying the surface of the carbon fiber tow, (ii) coating the oxidation-modified carbon fiber with a graphene oxide dispersion and drying to obtain carbon fiber coated with graphene oxide, (iii) placing the plurality of graphene oxide-coated carbon fibers in a solvent to swell the surface, bundling the swollen fibers, drying at less than 100 degrees C and volatilizing the solvent and (iv) reducing; (2) the graphene crosslinked carbon fiber fabric, where the surface of the carbon fiber has graphene sheets distributed along the axial direction of the fibers, the carbon fiber surfaces and the graphene sheets are connected by van der Waals force and hydrogen bonding at the fabric nodes and carbon fibers are crosslinked by graphene sheets; and (3) preparing the graphene-crosslinked carbon fiber fabric, comprising removing the sizing agent on the surface of the carbon fiber, oxidizing and modifying the surface of the carbon fiber fabric, coating the oxidation-modified carbon fiber with a graphene oxide dispersion and drying to obtain carbon fiber coated with graphene oxide, placing the plurality of graphene oxide-coated carbon fibers are woven into a fabric in a solvent to swell and fuse the surface, drying at less than 100 degrees C and volatilizing the solvent and reducing.
