亲水性微孔聚合物膜的亚纳米尺寸的受限通道中的离子和水传递在解决能源和环境相关膜技术的渗透性和选择性之间的普遍权衡方面显示出巨大的潜力。为此，已经开发了各种具有固有微孔性的亲水性聚合物（HPIM）。本文总结了HPIM的合成策略，包括聚合物的合成后改性以引入极性基团（例如，胺、羟基、羧酸、四唑）或带电部分（例如，季铵盐、磺酸）和亲水性单体的聚合。在能量转换和储存、酸性气体捕获和分离、离子二极管和超滤等方面，HPIM膜的优势突出。
Ion and water transfer in subnanometer‐sized confined channels of hydrophilic microporous polymer membranes show enormous potential in tackling the ubiquitous trade‐off between permeability and selectivity for energy and environment‐related membrane technologies. To this end, a variety of hydrophilic polymers of intrinsic microporosity (HPIMs) have been developed. Herein, the synthetic strategies toward HPIMs are summarized, including post‐synthetic modification of polymers to introduce polar groups (e. g., amines, hydroxy groups, carboxylic acids, tetrazoles) or charged moieties (e. g., quaternary ammonium salts, sulfonic acids), and the polymerization of hydrophilic monomers. The advantages of HPIM membranes over others when employed in energy conversion and storage, acid gas capture and separation, ionic diodes, and ultrafiltration, are highlighted.
