NOVELTY - Graphene/polyacrylonitrile fiber, which is a copolymer of polyacrylonitrile, nanographene and sub-micron graphene. USE - Used as graphene/polyacrylonitrile fiber. ADVANTAGE - The fiber has antistatic, high-strength, antibacterial and other functions. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a spinning stock solution for preparing the graphene/polyacrylonitrile fiber; and (2) preparing the spinning stock solution comprising firstly taking part of a solution uniformly dissolved in polyacrylonitrile solution, uniformly mixing the solution uniformly dispersed with nano-graphene and sub-micron graphene to prepare a spinning precursor solution, taking part or all spinning precursor solution and uniformly dissolving the remaining solution in which the polyacrylonitrile is uniformly dissolved to obtain the spinning stock solution.
