Polymers of intrinsic microporosity (or PIMs) provide porous materials due to their highly contorted and rigid macromolecular structures, which prevent space-efficient packing. PIMs are readily dissolved in solvents and can be cast into robust microporous coatings and membranes. With a typical micropore size range of around 1 nm and a typical surface area of 700-1000 m g, PIMs offer channels for ion/molecular transport and pores for gaseous species, solids, and liquids to coexist. Electrode surfaces are readily modified with coatings or composite films to provide interfaces for solid|solid|liquid or solid|liquid|liquid or solid|liquid|gas multiphase electrode processes.
固有微孔聚合物（或PIMs）由于其高度扭曲且刚性的大分子结构而提供多孔材料，这种结构阻碍了高效的空间堆积。PIMs很容易溶解在溶剂中，并可浇铸成坚固的微孔涂层和膜。PIMs的典型微孔尺寸范围约为1纳米，典型表面积为700 - 1000平方米/克，它为离子/分子传输提供通道，为气态物质、固体和液体共存提供孔隙。电极表面很容易用涂层或复合膜进行修饰，以提供用于固|固|液或固|液|液或固|液|气多相电极过程的界面。
