▎ 摘　　要

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).
