Abstract

Self-healing polymeric materials are intelligent materials engineered to autonomously repair damages using external stimuli which are the vanguard of sustainable materials research. The ability to maintain product quality and functionality, extended lifespan of products and cost-effectiveness play a significant role for the development of self-healing polymers (SHPs) and all of which substantially reduce the environmental impact of plastic waste. Over the years, Reversible Deactivation Radical Polymerization (RDRP) techniques, such as Nitroxide-mediated radical polymerization (NMP), Atom Transfer Radical Polymerization (ATRP), Reversible Addition-Fragmentation Chain Transfer (RAFT) polymerization and Ring-Opening Metathesis Polymerization (ROMP) have been widely used to synthesize SHPs with precise control over the molecular weight, distribution, architecture and functionality. Despite their potential, there is no comprehensive review that addresses the synthesis, advantages and applications of SHPs via RDRP methods. This review fills that gap by presenting detailed case studies that elucidate the unique properties and applications of SHPs synthesized through RDRP methods. The primary goal of this review is to provide a comprehensive perspective on the design of SHPs using various RDRP techniques, highlighting how these methods enable the preparation of SHPs with controlled architectures. Case studies of various RDRP techniques like ATRP, RAFT, NMP and ROMP are described, exhibiting their application in different healing mechanisms, such as reversible Diels-Alder (DA) and retro-DA (rDA) reactions, π-π interactions, hydrogen bonding and encapsulated microcapsules. By bridging the gap between fundamental RDRP techniques and practical applications of SHPs, this review aims to guide researchers and industry professionals in developing next-generation materials with enhanced self-healing capabilities.

通过可逆失活自由基聚合（RDRP）实现自愈合聚合物（SHPs）：合成、性能和应用。

自愈合聚合物材料是一种智能材料，可利用外部刺激自主修复损坏，是可持续材料研究的先锋。自愈合聚合物（SHPs）能够保持产品质量和功能、延长产品寿命并具有成本效益，这对自愈合聚合物的发展起着重要作用，同时也大大减少了塑料废弃物对环境的影响。多年来，可逆失活自由基聚合（RDRP）技术，如亚硝基自由基聚合（NMP）、原子转移自由基聚合（ATRP）、可逆加成-断裂链转移（RAFT）聚合和开环偏聚（ROMP）已被广泛用于合成可精确控制分子量、分布、结构和功能的自修复聚合物。尽管这些方法很有潜力，但目前还没有一篇全面的综述论述通过 RDRP 方法合成 SHPs 的合成、优势和应用。本综述通过详细的案例研究，阐明了通过 RDRP 方法合成的 SHP 的独特性质和应用，从而填补了这一空白。本综述的主要目的是全面介绍使用各种 RDRP 技术设计 SHP 的情况，重点介绍这些方法如何制备具有可控结构的 SHP。文中介绍了各种 RDRP 技术（如 ATRP、RAFT、NMP 和 ROMP）的案例研究，展示了它们在不同愈合机制中的应用，如可逆 Diels-Alder (DA) 和 retro-DA (rDA) 反应、π-π 相互作用、氢键和封装微胶囊。通过缩小 RDRP 基础技术与 SHP 实际应用之间的差距，本综述旨在指导研究人员和行业专业人员开发具有更强自愈能力的下一代材料。
