Polyphenylsulfone (PPSU) membranes are of fundamental importance for many applications such as water treatment, gas separation, energy, electronics, and biomedicine, due to their low cost, controlled crystallinity, chemical, thermal, and mechanical stability. Numerous research studies have shown that modifying surface properties of PPSU membranes influences their stability and functionality. Therefore, the modification of the PPSU membrane surface is a pressing issue for both research and industrial communities. In this review, various surface modification methods and processes along with their mechanisms and performance are considered starting from 2002. There are three main approaches to the modification of PPSU membranes. The first one is bulk modifications, and it includes functional groups inclusion via sulfonation, amination, and chloromethylation. The second is blending with polymer (for instance, blending nanomaterials and biopolymers). Finally, the third one deals with physical and chemical surface modifications. Obviously, each method has its own limitations and advantages that are outlined below. Generally speaking, modified PPSU membranes demonstrate improved physical and chemical properties and enhanced performance. The advancements in PPSU modification have opened the door for the advance of membrane technology and multiple prospective applications.
聚亚苯基砜（PPSU）膜由于其低成本、可控的结晶度、化学、热和机械稳定性，在许多应用中具有至关重要的意义，如水处理、气体分离、能源、电子和生物医学等领域。大量的研究表明，改变PPSU膜的表面性质会影响其稳定性和功能。因此，PPSU膜表面的改性对于科研界和工业界来说都是一个紧迫的问题。在这篇综述中，从2002年开始，我们考虑了各种表面改性方法和工艺及其机理和性能。PPSU膜的改性主要有三种方法。第一种是本体改性，包括通过磺化、胺化和氯甲基化引入官能团。第二种是与聚合物共混（例如，与纳米材料和生物聚合物共混）。最后，第三种方法涉及物理和化学表面改性。显然，每种方法都有其自身的局限性和优点，如下所述。一般来说，改性后的PPSU膜表现出改善的物理和化学性质以及增强的性能。PPSU改性方面的进展为膜技术的进步和多种潜在应用打开了大门。
