Surface Modification of Polymers: Methods and Applications

Low cost, controlled crystallinity, chemical, and mechanical stability enable application of polymers in energy, water, electronics, and biomedical industries. Recent studies have shown that tailoring surface properties of polymers impacts their durability and functionality in these applications. However, the functionality and performance of polymer‐based devices and systems are greatly affected by the modification method and the process parameters, highlighting the need for understanding these methods and their mechanisms of operation in detail. The selection of the modification method invariably decides the properties enhanced in the polymer. In this review, various polymer surface modification treatments are discussed. These methods are categorized into physical, chemical, thermal, and optical ways, while illustrating their advantages and disadvantages. This review also explores the surface modification of polymers by patterning which encompasses one or more surface treatment methods. An application‐oriented study is presented discussing the relative importance of a method pertaining to a specific field of end‐application. Surface modification of polymers is vital to render functionally robust and efficient surface morphologies and properties for targeted applications. This review explores major polymer surface treatment methods while discussing their advantages and disadvantages from a critical application viewpoint. Changes to surface roughness and energies are explored via various invasive and noninvasive treatment methods.
