Summary: | The invention discloses a preparation method for an inorganic / organic multilayer composite separator. The method comprises: soaking a separator in an organic solvent, cleaning surface of the separator by using ultrasonic vibration for 15 ~ 30min, drying in an oven, and then cutting the separator into a square separator; placing the above square separator and a target material into a RF (radio frequency) sputtering device; adjusting the air pressure of the RF sputtering device to be 0.1 ~ 1.0Pa, and then feeding in reactant gas, the sputtering power being 5 ~ 80W and the sputtering time being 5 ~ 100min; running the device, so target material plasma bombards gas molecules to form inorganic matter / organic matter which deposit on both sides of the separator to obtain an inorganic / organic multilayer composite separator. By uniformly sputtering one layer or a plurality of layers of inorganic matter / organic matter on the porous separator surface, the dimensional stability of ordinary separators is effective |
