Gas Separation Properties in a Few Layer Graphene/Polymer thin film Composite |
| 초록 |
Recently atomic layered 2D graphene sheets have keenly attracted in many important technological applications such as electronic devices, biosensor, and membrane-based separation processes. One of potential applications is to use gas-selective atomic layer as a high-selective membrane for gas separation. The main idea is to achieve the selective membrane layer with a few atom thick for high selectivity. In this study we demonstrate graphene multi-layered membranes densely stacked using 2D graphene sheets deposited in polymeric film for size-sieving separation mechanism in gas separation. We have achieved defect-free multi-layered/polymer composite membranes for gas separation by controlling the effective pathway between such multi-layered sheets via grain boundary in poly-crystalline graphene. It might be a promising material in the field of membrane science and technology. |
