Research Progress in Gas Separation Composite Membranes for Carbon Capture
Membrane separation technology has received wide attention in the field of carbon capture due to its advantages of high selectivity,low cost,green and non-polluting.Composite membranes,due to their ultrathin separation layer structure,show performance advantages in gas separation that homogeneous membranes do not have.This review introduces the principle of gas separation by membrane method and the composite membrane materials currently used in carbon capture technology,and summarizes the applications of composite membranes for carbon capture and their research progress at home and abroad.Finally,it analyzes the challenges and future development direction of composite membranes in the field of carbon capture.
