Abstract

Surface‐grafted polymer brushes (PBs) are a versatile class of thin coatings that exhibit unique properties due to their densely grafted polymer chains. PBs are typically formed through surface‐initiated polymerizations, particularly reversible deactivation radical polymerizations, and macromolecules adopt extended conformations that differentiate them from classical polymer films. This review explores various applications of PBs, emphasizing their macromolecular ordering, dynamic conformational changes, anisotropic properties, and so forth. The growing interest in utilizing PBs for functional coatings is discussed in various fields, including electronic, biological, and environmental applications. In electronic applications, PBs find relevance in photovoltaics, energy storage devices, organic light‐emitting diodes, and organic electronics, showcasing their potential in advancing electronic technologies. In biological applications, they contribute to the formation of antifouling and antibacterial coatings, as well as superior lubrication and cellular adhesion, making them valuable in biomedical settings. Other applications include biosensors, bioimaging systems, and drug delivery systems, highlighting their significant contributions to medical advancements. Additionally, PBs play an important role in environmental applications such as water and wastewater treatment. A variety of recent examples of the applications of surface‐grafted PBs are presented, providing insights into their unique properties and architectures that contribute to their success in demanding areas of science and technology.
