▎ 摘  要

NOVELTY - Pore-filled composite ion exchange membrane comprises a porous support containing an inorganic material in the pores; sulfone-based anionic monomers or ammonium-based cationic monomers including olefins; and a crosslinking agent. The porous support includes polyethylene, polyolefin, polyester, polysulfone, polyimide, polyetherimide, polyamide, polytetrafluoroethylene and/or rayon. The sulfone-based anionic monomer containing olefin includes sulfone-based anionic monomer containing olefin made of acrylamide/acrylate/vinyl/aryl/ stalen group. The ammonium-based cationic monomer containing olefin includes ammonium-based cationic monomer containing an olefin made of acrylamide/acrylate/vinyl/aryl/stalen group. USE - The ion exchange membrane is useful for reverse electrodialysis or flow electrode-capacitive mixing device (claimed). ADVANTAGE - The ion exchange membrane improves power density performance of electrochemical salt gradient power generation, and ensures simple impregnation of inorganic dispersion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing pore-filled composite ion exchange membrane.
