Abstract: |
|
Membrane-based gas separation had a variety of industrial applications such as chemical engineering, medical, environment, energy and so on. Polymer membrane is one of the most important parts in gas separation membranes. Recently, the emerging of polymer of intrinsic microporosity (PIM), a special polymer composed of “kinked” structure unit combined by some very rigid connectors. The site-of-contortions prevent the polymer main chain from close packing in the condensed phase that resulting in large volume of micropore (diameter < 2 nm). Besides, PIMs also demonstrate good mechanical strength, excellent solubility, thermal stabilities, etc., that are attracting great attention in both industrial and academic research. PIMs combined the advantages of easy processibility for polymer membranes and high permeability and selectivity of inorganic molecular sieve membranes, which demonstrated great potential in gas and liquid molecular separations. This review summarized the classification, synthesis and gas separation properties of intrinsically microporous polymers in gas field, and the perspective of this material. |
