Abstract
⺠Thermotreated hyperbranched polyimide membranes for gas separation were investigated. ⺠The thermotreated membranes showed high gas permeability and selectivity. ⺠The CO2/CH4 separation ability was improved by hybridization with silica. ⺠The improved separation ability were caused by enhanced free volume elements.
