Fabrication Strategies of Conjugated Microporous Polymer Membranes for Molecular Separation

Saving the energy consumption of the industrial separation process provides an effective way to alleviate the global energy shortage issue.Compared with traditional separation technology, membrane separation possesses low energy consumption and high economic benefits.The exploration of high-efficiency membrane materials is the key strategy to elevate membrane separation performance.Conjugated microporous polymer (CMP) membranes exhibit merits such as rigid and permanent micropores, high porosity, adjustable pore structure and pore environment, and good structural stability, which play vibrant role in molecular separation.In this review, we summarized the fabrication methods of CMP membranes with their advantages and challenges; introduced the research progress and mechanism in molecular separation field, including gas separation, organic solvent nanofiltration, ion sieving and chiral separation, over the recent years, which may provide ideas for designing new CMP membranes with high performance for crucial separation processes.
