Abstract

PURPOSE:To obtain the title functional separation membrane having a separation layer with high separation factor and permeation rate by using a nonwoven fabric with the surface having specified Bekk smoothness as the base material layer. CONSTITUTION:A nonwoven fabric such as a wet-type nonwoven fabric made of, for example, polyester fiber with the surface having >=10S Bekk smoothness is used as the base material layer 1. A soln. of, for example, sulfone in N,N- dimethylformamide is applied thereon, the material is immediately dipped in water to solidify the soln. and to remove the solvent, and a porous layer 2 is formed. A cross-linked silicone film is formed on the porous layer 2 as a substrate layer 3 by the coating method. The soln. of poly(4-methylpentene-1) in cyclohexane diluted with freon is applied on the substrate layer 3 as a separation layer 4, and then dried to produce a gas separation membrane.
