Ultrathin graphene oxide (GO) (<5 nm) membranes were prepared by spin-casting onto microporous polymeric support membranes. GO membranes exhibited a highly CO2 permeable character, which is suitable for CO2 separation. In the presence of water vapour, high CO2 selectivity (e.g., CO2/H2, CO2/N2, and CO2/CH4) was achieved by enhanced CO2 sorption.
通过旋涂法将超薄氧化石墨烯（GO）（<5纳米）膜制备在微孔聚合物支撑膜上。GO膜表现出高度的二氧化碳渗透性，适用于二氧化碳分离。在水蒸气存在的情况下，通过增强二氧化碳吸附实现了高二氧化碳选择性（例如，二氧化碳/氢气、二氧化碳/氮气和二氧化碳/甲烷）。
