| Abstract | The invention provides a method for forming an asymmetric polytetrafluoroethylene porous membrane. The method can simply produce an asymmetric polytetrafluoroethylene porous membrane and optimizes membrane performance. The method provided by the invention is realized through the following technical scheme: a symmetry polytetrafluoroethylene porous membrane is subjected to multiple extrusion treatments between a steel roller and a rubber roller; the rubber roller has surface hardness of 30-60A; and the extrusion treatment comprises conditions of: temperature of 20-250 DEG C, pressure of 46-90N / cm, speed of 0.9-1.8m / min and extrusion for 3-20 times. |
