▎ 摘  要

NOVELTY - The present invention discloses a method for manufacturing a composite fiber with high specific capacitance. After mixing polyacrylonitrile and polyacrylonitrile grafted graphene oxide polymer with polyvinylpyrrolidone and performing electrospinning, the polyvinylpyrrolidone is then removed. In order to increase the pores, and then through high temperature to form a carbonized composite fiber. In addition, the present invention also discloses another method is to mix polyacrylonitrile, benzoxazine and polyvinylpyrrolidone and perform electrospinning, then remove the polyvinylpyrrolidone, and after carbonization at high temperature, the benzoxazine ring opens The latter structure can effectively reduce heat shrinkage and increase pores, thereby providing electrode materials with excellent capacitance performance.
