Abstract: The continuous increase in oil price, combined with global warming caused by the emission of greenhouse gases, has led to the growing interest in searching for alternative energy sources and advanced technologies to reduce the emission of carbon dioxide. Membrane technology has shown great advantages over other conventional methods for capturing CO2 and producing green fuels such as H2. In this study, novel membrane materials based on CO2-philic materials (Poly(ethylene oxide) and Ionic Liquid) have been developed. By employing simple material modification, the gas separation performance of the membranes has improved and the CO2 permeability has increased drastically without compromising selectivity of CO2/H2 and CO2/N2. In order to apply the newly developed materials in industrial applications, composite hollow fiber membranes were fabricated via continuous coating process. The membranes have shown promising gas separation performance in the applications of hydrogen purification and flue gas treatment.
