NOVELTY - Method for preparing conductive PTFE porous membrane involves (i) mixing the PTFE water dispersion emulsion, polyvinyl alcohol solution and conductive material uniformly to prepare a spinning solution, and using the electrostatic spinning method to prepare the nascent polytetrafluoroethylene nanofiber membrane, (ii) immersing the nascent PTFE nanofiber membrane in the step (i) in a solution containing conductive material, and simultaneously loading the conductive material on the surface and inside of the nascent PTFE nanofiber membrane during the dipping process and (iii) extruding the excess dispersion medium and conductive material on the surface of the film obtained in the step (ii), heating and pressing the film to make each layer of conductive material inside the film. USE - Method for preparing conductive PTFE porous membrane. ADVANTAGE - The method is simple, and easy to industrialize production.
