▎ 摘　　要

NOVELTY - Method for preparing porous doped flexible activated carbon gas adsorption film, involves (a) completely dissolving polyacrylonitrile powder and graphene oxide of different qualities in N,N-dimethylformamide solvent, (b) electrospinning the obtained solution after completely dissolving in the above step (a) under different conditions and vacuum drying to obtain polyacrylonitrile/graphene oxide fiber film, and (c) subjecting the fiber film to pre-oxidation and carbonization activation treatment under different conditions to obtain the product. USE - The method is useful for preparing porous doped flexible activated carbon gas adsorption film for gas adsorption. ADVANTAGE - The adsorption film exhibits excellent gas adsorption performance, ensures simple operation and high product purity, and reduces preparation cost.
