首次通过将GO嵌入市售的聚环氧乙烷-聚对苯二甲酸丁二醇酯(PEO-PBT)共聚物(PolyActive(TM))中制备了CO2选择性氧化石墨烯(GO)纳米复合膜。所制备的 GO 膜具有高 CO2 渗透性 (143 Barrer) 和 CO2/N-2 选择性 (α = 73)。
CO2-selective graphene oxide (GO) nano-composite membranes were prepared for the first time by embedding GO into a commercially available poly(ethylene oxide)-poly(butylene terephthalate) (PEO-PBT) copolymer (PolyActive (TM)). The as-prepared GO membrane shows high CO2 permeability (143 Barrer) and CO2/N-2 selectivity (alpha = 73).
