Researches on methods, mechanisms, and modifications of membranes for CO₂ separation are overviewed, including common membrane materials with high CO₂ separation performance and membrane separation technologies. The great potential in all economy, safety, and environmental aspects as well as the prospects of membrane technology development for CO₂ separation are evaluated and critically discussed.

Abstract

Membrane fabrication methods, mechanisms, and modification of membranes for CO₂ separation are discussed. Various types of membrane materials with high CO₂ separation performance are summarized. Rapid prototyping can achieve precise control of the thickness of membranes and freely design the spatial structure of membranes, which provides a new development direction for material application and process combination. Hence, a critical comparison of membrane fabrication using different methods can provide a comprehensive overview on the potential of the rapid prototyping technology in membrane fabrication. This is important to demonstrate the prospects of the membrane technology development for CO₂ separation.
