▎ 摘  要

NOVELTY - A material is prepared by: (1) preparing a graphene by heating a graphene raw material in a concentrated sulfuric acid and concentrated nitric acid water bath to obtain carboxylated graphene, followed by ultrasonically dispersing the carboxylated graphene in a certain amount of sodium dodecyl sulfonate, drying and grinding; (2) preparing a graphene fiber by taking the graphene obtained in step (1) and cellulose as raw materials and using microfluidic technology; (3) performing modification of the graphene fiber by cutting the graphene fiber on a cutting table, dipping the cut graphene fiber in organic solvents, ultrasonically processing, adding phenolic resin and a curing agent, again dipping and drying to obtain modified graphene fibers; (4) carrying out prefabrication by welding the modified graphene fiber obtained in step (3) into a monolithic block, and then pre-shaping the block to get a preform; and (5) curing. USE - The material is useful for a battery shell of a new energy vehicle. DETAILED DESCRIPTION - A material useful for a battery shell of a new energy vehicle is prepared by: (1) preparing a graphene by heating a graphene raw material in a concentrated sulfuric acid and concentrated nitric acid water bath to obtain carboxylated graphene, followed by ultrasonically dispersing the carboxylated graphene in a certain amount of sodium dodecyl sulfonate, drying under vacuum and grinding; (2) preparing a graphene fiber by taking the graphene obtained in step (1) and cellulose as raw materials and using microfluidic technology; (3) performing modification of the graphene fiber by cutting the graphene fiber on a cutting table, dipping the cut graphene fiber in organic solvents, ultrasonically processing, adding phenolic resin and a curing agent, again dipping under room temperature and atmospheric pressure, and drying to obtain modified graphene fibers; (4) carrying out prefabrication by welding the modified graphene fiber obtained in step (3) into a monolithic block by ultrasonic welding technology, and then pre-shaping the block to get a preform; and (5) curing by placing the preform in a mold, adding phenolic resin, the curing agent and an additive, dipping, and heat curing.
