A series of mixed matrix membranes (MMMs) with ethyl cellulose (EC) as matrix and melamine as modifier in tetrahydrofuran(THF)were prepared under high speed and ultrasonic vibration-assisted,by using the casting solution method.The melamine/EC membranes exhibited good membrane forming ability,heat resistance and mechanical properties.The successful melamine/EC mixed matrix membranes were confirmed by fourier transfer infrared (FT-IR).The CO2 permeability of the CO2/CH4 mixture was 85.9 Barrer,respectively,increased up to 1.9 times as compared to pure EC (45.3Barrer).The CO2 permeability of the CO2/N2 mixture was 96.4 Barrer,respectively,increased up to 2.1 times as compared to pure EC (45.4 Barrer).
