The invention discloses a method for preparing a G / Sn / PAN-base carbon nanometer
fiber membrane. The method for preparing the G / Sn / PAN-base carbon nanometer
fiber membrane includes: 1) preparing
spinning solution, to be more specific, weighing
polyacrylonitrile, nanometer
tin powder and
graphene nanometer film according to certain
mass ratio, blending and dissolving in N-N
dimethyl formamide, and stirring to obtain the uniformly dispersed electrostatic
spinning solution; b) electrostatic
spinning, to be more specific, carrying out electrostatic spinning on the electrostatic spinning solution of the step a) to obtain a
graphene /
tin /
polyacrylonitrile nanometer
fiber membrane; c) pre-oxidizing, to be more specific, pre-oxidizing the
graphene /
tin /
polyacrylonitrile nanometer fiber membrane of the step b) in
air atmosphere to obtain the pre-oxidized nanometer fiber membrane; d) carbonizing, to be more specific, carbonizing the pre-oxidized nanometer fiber membrane in
argon atmosphere to obtain the G / Sn / PAN-base carbon nanometer fiber membrane. The method for preparing the G / Sn / PAN-base carbon nanometer fiber membrane is easy to operate, the graphene coats the nanometer fiber well; the G / Sn / PAN-base carbon nanometer fiber membrane has advantages of large specific surface area, high
porosity, and high electrical
conductivity and so on, and has broad expanding space.
