▎ 摘  要

NOVELTY - Preparing graphene/polyacrylonitrile spinning stock solution comprises (1) carrying copolymerization on acrylonitrile and methyl ester; (2) preparing polyacrylonitrile resin filter cake; (3) adding graphene suspension solution, and blending; (4) mixing with concentrated sodium thiocyanate (NaSCN) solution and high shear dispersion; (5) defoaming and dehydrating; and (6) filtrating. USE - The method is useful for preparing graphene/polyacrylonitrile spinning stock solution. ADVANTAGE - The spinning stock solution: has good spinnability, and graphene can be uniformly and stably disperse in spinning solution for more than 48 hours; and can prepares graphene/polyacrylonitrile fiber having specific resistance increased by 3 orders of magnitude, and strength is increased by more than 20%.
