Graphene oxide (GO) is a 2-dimensional material that has a great potential in many applications. GO is impermeable to gases and liquids thus GO has been reported application in gases and liquids protection. Meanwhile, recently GO can also exhibits gas separation characteristics by adjusting stacking structure of GO sheets onto membranes. In this study, our groups introduce GO/polymer membranes for CO2 separation. The main idea of GO/polymer membranes is internal structure and composition of layer-by-layer self-assembled GO/polymer multilayer film. Even though thickness of GO layer is lesser than 50nm, GO membranes have great selectivity of CO2. In addition, positively charged amine groups in polymer layer are expected to facilitate CO2 transport and enhance the separation performance. |
