In this study, a nanocomposite graphene oxide (GO) incorporated poly (dimethyl siloxane) (PDMS) membrane was produced and used for the purification of hydrogen (H₂₎ by separating the (CO₂). The produced membrane was characterized and the single-gas permeability test was performed. Effects of GO addition, trans-membrane pressure and membrane thickness on the gas separation performance of membrane were evaluated as a function of permeability and CO₂/H₂ selectivity. GO addition increased the CO₂/H₂ selectivity and H₂ purification performance. The highest CO2 permeability of 3670 Barrer and CO₂/H₂ selectivity of 11.7 were obtained when the GO loading was 0.5 wt% when the trans-membrane pressure was 0.2 Mpa.

在这项研究中，纳米复合材料的氧化石墨烯（GO）并入聚（二甲基硅氧烷）（PDMS）膜生产和使用氢的纯化（H _2）通过分离（CO ₂）。对制得的膜进行表征，并进行单气体渗透性测试。评价了GO的添加，跨膜压力和膜厚度对膜的气体分离性能的影响，其作为渗透率和CO ₂ / H ₂选择性的函数。GO的添加提高了CO ₂ / H _2的选择性和H _2的纯化性能。最高的CO2渗透性为3670 Barrer和CO ₂ / H ₂ 当跨膜压力为0.2 Mpa时GO负载为0.5 wt％时，选择性达到11.7。
