NOVELTY - Preparation of continuous spinning nanofiltration base film involves (i) mixing hydrophilic inorganic nanoparticles and film-forming polymer by ball milling to obtain uniformly mixed material, and (ii) preparing hollow fiber nanofiltration film by extruding, granulating to obtain uniformly mixed particles, passing particles through extruder, extruding filter screen, filling spinneret with inert gas, stretching, cooling and solidifying in coagulating bath, winding after stretching in air and performing heat setting. USE - Preparation of continuous spinning nanofiltration base film. ADVANTAGE - The method is environmentally-friendly and enables preparation of continuous spinning nanofiltration base film having excellent strength and without diluent addition.
