Advanced Functional Membrane for CO2 Capture

The capture of carbon dioxide directly from the air has been shown a growing interest in the mitigation of greenhouse gases but remains controversial among the research community. Due to the high dilution factor of CO2 in air, simultaneously increases the energy requirement as well as the charge of the respective technology. Membrane/Thin film technology has been conceded as the most investigated as well as most appealing technology to attenuate carbon dioxide from the atmosphere. The membrane and membrane process technique are found to be alluring and eco-friendly to mitigate the carbon due to its cost efficiency, low expenditure of energy as well as comprehensibility in operation. Traditionally, the materials are cast into dense membranes with a standard thickness and after the formation of the membranes, their applications such as carbon capture/separation are evaluated by commutation between permeability and selectivity. In present scenario, efficient separation of CO2 from other gases has become a worldwide issue. Coal/Natural/Flue gases are evolving as the primary source of CO2, so the capture of CO2 from the mentioned sources are extensively contemplated as the next opportunity for the large-scale deployment of gas separation membranes. Although, current researches indicate the advances in material process designs that can crucially enhance the membrane capture systems as well as the separation systems, which make membrane process technique contentious with other technologies present till date for carbon capture. The aforementioned application requires novel polymeric materials which have the ability for efficient carbon capture and possesses high CO2 separation properties from different mixed gases, along with high mechanical and thermal stability for a longer time. Herein, the present report precisely highlights the recent advancement on the membrane technology based on the functional materials and their applications in the field of CO2 capture.
