Fabrication process and structure diagram of the ultrathin GO-based hollow fiber membranes with brush-like CO2-philic agent. The blue brushes denote the grafted agents on the top surface of GO, and the red brushes denote the grafted agents on the bottom surface of GO. The brushes can be appropriate CO2-philic agents that are able to chemically bond with the GO surface by reacting with oxygen-functional groups
