Abstract
Mixed Matrix Membranes (MMMs) have combination benefits of both polymer substrates and porous nanoparticles and have become interesting membranes for gas separation. Nanoparticles can improve not only gas separation performance but also physical properties (e.g., mechanical strength, thermal stability, and physical aging). Actual flue gas situation involves various minor components as impurity such as water vapor, inert gases, carbon dioxide, hydrocarbons, sour gases, etc. The influence of these components on the membrane performance appears as membrane swelling, plasticization, and chemical/physical aging. This paper describes development of MMMs for carbon capture and their interesting properties as gas separation membranes. The impacts of minor components in the feed gas stream on the membrane performance of MMMs are also introduced.
