▎ 摘　　要

NOVELTY - Preparation of graphene/tin/polyacrylonitrile (G/Sn/PAN) carbon nanofibrous membrane comprises weighing PAN, Sn nanopowder and G nanosheet, mixing in N,N-dimethylformamide, stirring, uniformly dispersing to obtain spinning solution, electrospinning spinning solution to obtain G/Sb/PAN membrane, pre-oxidizing in air atmosphere to obtain pre-oxidized nanofibrous membrane and carbonizing with silicon carbide in argon atmosphere. USE - Method for preparing G/Sn/PAN carbon nanofibrous membrane (claimed). ADVANTAGE - The nanofibrous membrane has large specific surface area, high porosity and electrical conductivity, and good expanding space. The method is simple.
