| titleOfInvention | Hydrophilic polyimide porous membrane and method for producing the same |
| abstract | The present invention provides a polyimide porous film which has good wettability to water on the surface and the surface of internal pores, can be expected to have chemical reactivity on the surface and the surface of internal pores, and has excellent heat resistance, and a method for producing the same. The porous structure has pores on both surfaces and a continuous pore structure bent inside, and further has a hydrophilic group, preferably a carboxyl group (-COOH), a hydroxyl group (-OH), a sulfonic acid group ( A porous polyimide membrane having a polar group such as —SO 3 H), and a polyimide having a hydrophilic group in its primary structure or a precursor thereof as a starting material, with pores on both surfaces and a continuous pore structure bent inside. A method for producing a hydrophilic polyimide porous membrane, characterized by obtaining a porous membrane having [Selection diagram] None |
