▎ 摘　　要

NOVELTY - Preparation of single-layer porous graphene-reinforced carbon fiber fishing rod involves dispersing single-layer porous graphene in a sizing agent to obtain a graphene sizing system, immersing a carbon fiber tow in the graphene sizing system, to obtain a graphene-coated carbon fiber tow, placing the tow on an epoxy-coated release paper, extruding into a carbon fiber cloth, cutting the cloth, molding, and solidifying in a high-temperature curing oven. The single-layer porous graphene is prepared by subjecting ultrasonically treated graphene oxide-N-methyl-2-pyrrolidone (NMP) dispersion to microwave irradiation, such that NMP volatilizes and burns under the action of microwave, and graphene oxide undergoes reduction reaction under the action of heat generated by NMP combustion and re-expands to form a single-layer porous graphene precursor, mixing with 0.5-15 g potassium hydroxide, and activating in a tubular furnace at 400-1000 degrees C for 0.5-4 hours under nitrogen protection atmosphere. USE - Preparation of single-layer porous graphene-reinforced carbon fiber fishing rod. ADVANTAGE - The graphene and carbon fibers can form a continuous structure, thereby increasing the tensile bending strength of the single-layer porous graphene-reinforced carbon fiber fishing rod. The single-layer porous graphene can easily coat the carbon fibers, and provides sufficient passage for the circulation of the resin between the carbon fiber cloth during the curing process. DETAILED DESCRIPTION - The microwave irradiation treatment is carried out at 300-900 W for 3-10 minutes. The ultrasonically treated graphene oxide-NMP dispersion is prepared by single-layer porous graphene is prepared by adding 1-5 pts. wt. expanded graphite in 100 pts. wt. solvent containing 30-80 wt.% dispersing agent, performing high-speed shear stripping to peel the expanded graphite of the worm-like structure into 10 layers, obtaining graphene microchip dispersion, leaving still for 8-24 hours, collecting the upper layer stable dispersion, spray drying, obtaining graphene microchip powder, adding 1-3 g graphene microchip powder to 100-150 ml concentrated sulfuric acid, adding 5-20 ml 35-50% hydrogen peroxide solution while stirring, reacting at room temperature for 20-90 minutes to obtain a graphene oxide dispersion, washing with deionized water to neutral, and NMP until NMP completely replaces the deionized water in the graphene oxide dispersion to obtain graphene oxide-NMP dispersion, and ultrasonically treating for 1-6 hours. The solvent is one of deionized water, NMP and dimethylformamide. The dispersing agent is one of carboxymethyl cellulose, sodium dodecyl sulfate, polyvinylpyrrolidone and BYK-163 (RTM: high-molecular weight wetting and dispersing additive). The sizing agent is an epoxy resin. The weight ratio of single-layer porous graphene to the sizing agent is 1:100-1000.
