Recently, graphene oxide (GO) has been extensively investigated as a membrane material for gas and liquid separation because thin-film GO membranes show quite interesting separation performance. Although GO membrane has been extensively investigated for membranes due to its outstanding properties such as selective CO2 or water vapor transport properties, it has a limitation to apply for practical application because of low CO2 permeance because of high tortuosity caused by high aspect ratio of GO. Normally, the size of GO is in the range from a few hundred nanometers to a few micrometers, so inherent gas permeability would be varied. As such, in this study, we have modified the pristine GO sheets to reduce the gas permeation pathway, with maintaining GO’s excellent gas separation properties. This study will provide a further insight on how such two-dimensional nanosheets can be used for membrane applications, competing with existing membrane materials. |
