PURPOSE: To obtain a photocatalyst-immobilized membrane having photocatalytic function and usable in a fluid system, by immobilizing semiconductor powder to a porous polymer membrane. n CONSTITUTION: Powder of a semiconductor (e.g., oxide, etc., such as titanium dioxide or cadmium sulfide) is immobilized to a porous polymer membrane (e.g., polysulfone, cellulose acetate or polyvinyl alcohol) to obtain the objective membrane. The ratio of the semiconductor to the polymer in the membrane is preferably 30W200wt.%. n COPYRIGHT: (C)1989,JPO&Japio |
