The generation of polymer brushes by surface-initiated controlled radical polymerization (SI-CRP) techniques has become a powerful approach to tailor the chemical and physical properties of interfaces and has given rise to great advances in surface and interface engineering. Polymer brushes are defined as thin polymer films in which the individual polymer chains are tethered by one chain end to a solid interface. Significant advances have been made over the past years in the field of polymer brushes. This includes novel developments in SI-CRP, as well as the emergence of novel applications such as catalysis, electronics, nanomaterial synthesis and biosensing. Additionally, polymer brushes prepared via SI-CRP have been utilized to modify the surface of novel substrates such as natural fibers, polymer nanofibers, mesoporous materials, graphene, viruses and protein nanoparticles. The last years have also seen exciting advances in the chemical and physical characterization of polymer brushes, as well as an ever increasing set of computational and simulation tools that allow understanding and predictions of these surface-grafted polymer architectures. The aim of this contribution is to provide a comprehensive review that critically assesses recent advances in the field and highlights the opportunities and challenges for future work.
通过表面引发可控自由基聚合（SI-CRP）技术生成聚合物刷已成为一种调整界面化学和物理性质的有效方法，并在表面和界面工程领域取得了重大进展。聚合物刷被定义为薄的聚合物薄膜，其中各个聚合物链通过一个链端与固体界面相连。在过去的几年中，聚合物刷领域取得了重大进展。这包括 SI-CRP 的新发展，以及新型应用如催化、电子、纳米材料合成和生物传感的出现。此外，通过 SI-CRP 制备的聚合物刷已被用于修饰新型基底的表面，如天然纤维、聚合物纳米纤维、介孔材料、石墨烯、病毒和蛋白质纳米颗粒。近年来，聚合物刷的化学和物理特性的表征也取得了令人兴奋的进展，以及越来越多的计算和模拟工具，这些工具允许理解和预测这些表面接枝聚合物结构。本文的目的是提供一个全面的综述，批判性地评估该领域的最新进展，并强调未来工作的机遇和挑战。
