与传统的基于乙烯基的聚合物刷相比，非基于乙烯基的“接枝自”聚合物刷在过去十年中产生了很大的兴趣和增长，这是由于具有更刚性的主链、长程有序和新的主链官能团的潜力。聚合物刷的这一领域已经受到新聚合技术的最新进展的刺激，例如链增长缩聚，其允许传统逐步增长聚合物转化为所需的链增长聚合物以通过“接枝”技术形成聚合物刷[1]。这种令人兴奋的新型聚合物刷形成半柔性或刚性杆结构，其在各种应用中具有潜力，包括有机光致发光、有机发光二极管、摩擦涂层、用于水净化和脱盐的膜、用于燃料电池的膜、高性能涂层和生物传感，这是由于主链中的芳族基团、连接链的次级键合力或共轭主链[2]，[3]的文件。本文将重点介绍非乙烯基聚合物刷的合成和表征，主要是通过“接枝”技术制备的，同时还包括这些系统的潜在应用的概述，并突出未来发展的前景。
Non-vinyl-based ‘grafted from’ polymer brushes have generated much interest and growth in the past decade due to the potential for stiffer backbones, long-range order, and new backbone functional groups, compared to the traditional vinyl-based polymer brushes. This area of polymer brushes has been spurred on by recent advancements of new polymerization techniques, such as chain-growth condensation polymerization, that allow for the conversion of traditional step-growth polymers into the required chain-growth polymers to form polymer brushes via the ‘grafting from’ technique [1]. This exciting new category of polymer brushes forms semi-flexible or rigid-rod structures that have potential in a variety of applications including organic photovoltaics, organic light emitting diodes, tribological coatings, membranes for water purification and desalination, membranes for fuel cells, high performance coatings, and biosensing due to aromatic groups in the backbone, secondary bonding forces connecting chains, or conjugated backbones [2], [3]. This review will focus on the synthesis and characterization of non-vinyl-based polymer brushes, primarily prepared via the ‘grafting from’ technique, while also including an overview of potential applications of these systems and highlighting prospective areas for future developments.
