FILM FOR FILTRATION, GAS OR LIQUID SEPARATION, AND EVAPORATION DEVICE, AND MANUFACTURE OF THE SAME

摘要

PURPOSE: To produce a composite membrane for filtration having a uniform membrane thickness. CONSTITUTION: In the membrane for filtration, gas or liq. separation and evaporative separation device containing at least one porous layer consisting of an inorg. material selected from a sintered ceramic, sintered metal, sintered glass and carbon and a separation layer consisting of polyphosphazene, an average diameter of pores of the porous layer consisting of the inorg. material is 10 nm to 0.1 μm, and the separation layer is continuous and infiltrated into the inorg. layer of a thickness of 2-5 times to the pore diameter of the inorg. porous layer.
