A New Method for Mixed Matrix Composite Membranes Preparation Using Direct Spray‐Coating Technique
Greenhouse Gases: Science and Technology, EarlyView.ABSTRACT The development of membranes has evolved over the last years as an effective CO2 separation technology to fight the environmental impact of post‐combustion processes. In this regard, the upgrade of conventional polymers has been approached through different strategies to overcome their permeance‐selectivity trade‐off.
