Abstract: A film manufacturing equipment includes a transporting device, a filtering device, a coating device, a baking device and a blowing device. Transporting device is configured to transport a substrate. The filtering device is configured to filter a solution. The coating device is configured to squeeze and coat the filtered solution on the substrate. The baking device is configured to bake the solution coated on the substrate. The blowing device is configured to blow an air to the baked solution.

Abstract: A porous film and a method for manufacturing the same are provided. The method includes: using a ternary mixed solvent to dissolve a structural material selected from the group consisting of nitrocellulose, polyvinylidene fluoride, polysulfone, and any combination thereof and an auxiliary structural material selected from the group consisting of cellulose acetate, polylactic acid, poly(lactic-co-glycolic acid), poly-(D)glucosamine, and any combination thereof, so as to obtain a mixed solution; adding water into the mixed solution to obtain a film-forming solution; coating the film-forming solution onto a carrier substrate to form a wet film; and vaporizing the ternary mixed solvent and the water to form the porous film on the carrier substrate. The ternary mixed solvent, based on a total weight thereof being 100 phr, includes 28 phr to 38 phr of ethanol, 25 phr to 42 phr of isopropanol, and 25 phr to 40 phr of acetone.
