sulfonated PEEK blend membranes prepared with PPSF and PEI for gas separation

摘要

In recent years, with developing of membrane technology and increasing of usage area, researches about producing materials that have excellent properties gain important. The usage area of membrane material is filtration, reverse osmosis, dialyze, pervaporation and gas separation. Recent ten years, effective, economic and comfortable application of polymeric membranes is increased widely. Enrichment nitrogen and oxygen from air, separation of hydrogen from nitrogen, carbon monoxide and methane mixer, removing carbon dioxide from natural gas and removing volatile compounds from air are wide applications for commercial applications of polymer membranes. In these applications, polymer membranes are used with high fluxes and excellent selectivities confidently.
