A method for making a polyimide microporous separator comprising: using a flexible monomer to prepare a soluble polyimide by a one-step method, and forming a polyimide liquid solution; providing an inorganic template of inorganic nanoparticles, and surface treating the inorganic template with a surface treatment agent in an organic solvent to dissolve the inorganic template in the organic solvent, thereby forming an inorganic template liquid dispersion; mixing the polyimide liquid solution with the inorganic template liquid dispersion and agitation to form a film forming liquid; coating the film forming liquid on a substrate to form an organic-inorganic composite film; and disposing the organic-inorganic composite film into a template removing agent, the inorganic template in the organic-inorganic composite film reacting with the template removing agent to remove the inorganic template from the organic-inorganic composite film. |
