摘要 |
A composite fluid separation membrane having improved fluid permeabilities and a method for preparing same are disclosed. The composite fluid separation membrane is comprised of a porous support in the form of a flat sheet, tube or hollow fiber which is impregnated with a volatile solvent followed by the in situ formation of a separating layer wherein the preimpregnation of the pores of the porous support with the solvent provide a separating layer of substantially uniform thickness and minimum intrusion of the separating layer polymer into the pores of the porous support.
