| titleOfInvention | Hollow fiber-like amphoteric charged membrane and method for producing the same |
| abstract | [PROBLEMS] To easily and inexpensively produce a homogeneous amphoteric charged membrane that has excellent pressure resistance, durability, ion selectivity, etc., in particular, excellent salt permeability, and can be a module with a small installation area. And a method for providing an amphoteric charged membrane having these characteristics. Step (1): Mixing a film-forming polymer, a solvent capable of dissolving the film-forming polymer, and an ion exchange resin, and dispersing the ion exchange resin in the polymer solution to prepare a uniform polymer dispersion; And Step (2): The hollow fiber-like melt obtained by spinning the polymer dispersion is contacted with air and then immersed in pure water, and the solvent is removed from the obtained hollow fiber-like film and solidified. A method for producing a hollow fiber-like amphoteric charged membrane, wherein the ion exchange resin is a combination of a cation exchange resin and an anion exchange resin, or an amphoteric ion exchange resin, and Hollow fiber-like amphoteric charged membrane produced by the production method.
