High performance cyclic olefin copolymer (COC) membranes prepared with melt processing method and using of surface modified graphitic nano-sheets for H2/CH4 and H2/CO2 separation

- Surface nature of graphitic nano sheets was successfully modified with ODA and SA.
- COC based membranes were prepared by melt extrusion method.
- H2/CH4 selectivity value, about 500, was obtained by using of 5 wt% of GO-SA.
- COC based membranes exhibited high H2/CO2 separation performance by Doğu and Ercan.
