Abstract
A copolyimide nano-fiber non-woven fabric, a process for producing the same and the use thereof. The process comprises the following steps: tetracid dianhydride monomer and diamine monomer are polycondensated in the reaction medium of a high polar solvent under mechanical agitation to form a solution of a copolyamic acid; the copolyamic acid solution is electrostatically spinned under a high voltage electric field to give a non-woven fabric of a nano-fiber of the copolyamic acid; and then the non-woven fabric is imidized. The copolyimide nano-fiber non-woven fabric has features of a strong tear resistance, a high porosity, high/low-temperature resistances and excellent mechanical properties, etc., and can be used in battery membrane and capacitor membrane.
