Production of porous membrane |
| abstract |
PURPOSE: To obtain a porous membrane decreased in a pore diameter on the surface to which another substance is to be added and improved in permeability by casting an organic solvent solution of a film-forming polymer to which a fine water-soluble inorganic salt powder has been and immersing it in a coagulation bath. n CONSTITUTION: A film-forming dope is obtained by adding 1-30wt.% fine water- soluble inorganic salt powder (e.g., NaCl) of a particle diameter ≤150μm to a solution obtained by dissolving at most 30wt.% film-forming polymer (e.g., polysulfone) in an organic solvent. This dope is cast on a substrate and coagulated by immersion in a coagulation bath such as water. n COPYRIGHT: (C)1990,JPO&Japio |
