Footmarks of graphene nanocomposites towards carbon capturing—Next membrane materials

Abstract

Development of graphene nanocomposite membranes has gained increasing research attention owing to physical and operational benefits for technical applications. The surface structure and physicochemical features of graphene nanocomposite membranes have been found indispensable for carbon capture. This state-of-the art review article has covered the advancements of high performance graphene nanocomposite membranes regarding carbon capture. Preferably, graphene nanocomposite membranes have been focused for low price, fine microstructure, ease of fabrication, durability, robustness, and superior physical features. Graphene reinforcement has been used to enhance the performance of traditional membrane materials like polysulfone, poly(ether sulfone), polyvinylamine, and other matrices. Studies have revealed that the design, porosity, pore size, and pore distribution of graphene nanocomposite membranes can be altered to attain high permeability, selectivity, and CO2 capture and separation properties. Future smart carbon capture graphene membrane architectures can be focused with more defined and controlled pore size, distribution, nanostructure, and interactions towards carbon seizure.
