Poly(aryl sulfone) as a typical membrane material has been widely used due to excellent mechanical, chemical and thermal stability. However, the inherent hydrophobicity of poly(aryl sulfone) based membranes bears with the fouling issue during applications, which makes the membrane tending to adsorb contaminants on the surface so as to result in decreased separation performance and lifetime. In this critical review, we give a comprehensive overview on characterizations of hydrophilic membrane and diverse hydrophilic modification approaches of poly(aryl sulfone) membranes, predominantly including bulky, blending and surface modification technology. The discussions on the different modification methods have been provided in-depth. Besides, focusing on modification methods and performance of modified membranes, the related mechanisms for the performance enhancement are discussed too. At last, the perspectives are provided to guide the future directions to develop novel technology to manipulate the hydrophilicity of poly(aryl sulfone) membranes toward diverse practical and multifunctional applications.

聚（芳基砜）作为一种典型的膜材料，由于其优异的机械、化学和热稳定性而被广泛使用。然而，基于聚（芳基砜）的膜固有的疏水性在应用过程中存在污染问题，这使得膜倾向于吸附表面的污染物，从而导致分离性能和寿命降低。在这篇批判性评论中，我们全面概述了亲水膜的表征和聚（芳基砜）膜的多种亲水改性方法，主要包括大体积、混合和表面改性技术。深入讨论了不同的修改方法。此外，重点关注改性膜的改性方法和性能，还讨论了性能增强的相关机制。最后，提供了一些观点，以指导未来发展控制聚（芳基砜）膜亲水性的新技术，以实现多样化的实用和多功能应用。
