Novel multilayer mixed matrix zeolite polymerized room - temperature ionic liquid membrane for CO2/N2 and CO2/CH4 gas separation

摘要

A novel multilayer mixed matrix membrane, consisting of zeolite particles and polymerizable room temperature ionic liquids (RTILs) has been synthesized; and the potential for carbon dioxide separations are investigated. Previous studies have shown that mixed matrix membranes consisting of polymeric matrix and dispersed inorganic particles have the potential for outstanding separation properties; however some challenges such as high inorganic particles loading and a good adherence at the inorganic/organic interface still remain uncertain. On the other hand, polymerizable RTILs have demonstrated excellent gas separation properties.
