Removal of dyes from various industrial effluents is a great challenge, and cost-effective methods and materials with high dye removal efficacy are in high demand. Adsorption, nanofiltration and photocatalytic degradation are three major techniques that have been investigated for dye removal. PIMs are promising materials for use in these three methods based on their attributes, such as microporosity, solution processibility, high chemical stability and tunability through facile synthesis and easy postmodification. Although the number of reports on dye removal employing PIMs are limited, some of the materials have been shown to exhibit good dye separation properties, which are comparable to those of the state-of-the-art material activated carbon. In this highlight, we make an account of progress in PIMs and PIM-based composite materials in different dye removal processes over the last decade. Furthermore, we discuss the existing challenges of PIM-based materials and aim to analyze the key parameters for improving their dye removal properties.
从各种工业废水中去除染料是一项巨大的挑战，因此对具有高染料去除效率的经济高效方法和材料有很高的需求。吸附、纳滤和光催化降解是研究用于染料去除的三种主要技术。基于其微孔性、溶液可加工性、高化学稳定性以及通过简便合成和易于后修饰实现的可调性等特性，多孔有机聚合物（PIMs）是有望用于这三种方法的材料。尽管使用PIMs进行染料去除的报道数量有限，但一些材料已显示出良好的染料分离性能，可与最先进的材料活性炭相媲美。在本综述中，我们介绍了过去十年中PIMs和基于PIM的复合材料在不同染料去除过程中的进展。此外，我们讨论了基于PIM的材料目前存在的挑战，并旨在分析改善其染料去除性能的关键参数。
