Title: Hydrophilic selective transmitting membrane
Inventor: SHIODA YASUHIRO
IPC: B01D69/02
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To suppress elusion of hydrophilic polymers without requiring crosslinking by radiation or the like, to keep high safeness when a membrane is used, and to prevent changes in the separation characteristics with time by forming a uniform fine structure for the film structure of a selective transmitting membrane containing hydrophilic polymers. SOLUTION: This selective transmitting membrane consists of hydrophobic polymers such as polyethersulfone as the base material and contains hydrophilic polymers such as polyvinylpyrrolidone. It is required to wet the membrane for use because of its strong hydrophobicity, and in order to sufficiently wet the membrane, the membrane structure is formed as a uniform fine structure. Namely, the hydrophilic selective transmitting membrane as a film based on hydrophobic polymers and containing hydrophilic polymers is produced by using a non-solidifying inner liquid to form vacancies and then solidifying the membrane at <20 C solidifying bath temp. Enough hydrophilicity can be added to the selective transmitting membrane by forming a uniform fine structure of the membrane although the membrane contains a large amt. of hydrophobic polymers.
