FACILITATED OLEFIN TRANSPORT SEPARATION MEMBRANE INCLUDING ALUMINUM SALT

摘要

PROBLEM TO BE SOLVED: To provide a facilitated olefin transport separation membrane.SOLUTION: Provided herein is a facilitated olefin transport separation membrane, including: a porous support film; and a polymer electrolyte layer including a polymer and a silver salt of the prior art. In the membrane, an aluminum salt is used to eliminate the problem of reduction of the silver salt to silver nanoparticles deteriorating the performance of the separation membrane over time.
