Covalent cross-linking is a simple and robust way to stabilize block copolymer nano-assemblies prepared by reversible addition–fragmentation chain transfer polymerization mediated polymerization-induced self-assembly (RAFT-mediated PISA). To date, various multi-functional compounds with different reactive moieties have been explored for cross-linking of block copolymer nano-assemblies, and these cross-linking approaches can be classified into in situ cross-linking and post-polymerization cross-linking. Owing to the efficient and diverse operations of these cross-linking approaches, various cross-linked block copolymer nano-assemblies with complex morphologies have been constructed, exhibiting superior structural stability against solvent switching or external stimulus. The aim of this review is to summarize the current cross-linking approaches to stabilize block copolymer nano-assemblies obtained via RAFT-mediated PISA process as well as their potential applications.

通过RAFT介导的聚合诱导的自组装，对嵌段共聚物纳米组件进行交联的方法

共价交联是稳定可逆的加成-片段链转移聚合介导的聚合诱导的自组装（RAFT介导的自组装）制备的嵌段共聚物纳米组装件的简单而稳定的方法。迄今为止，已经探索了具有不同反应性部分的各种多功能化合物用于嵌段共聚物纳米组装件的交联，并且这些交联方法可以归类为原位。交联和后聚合交联。由于这些交联方法的有效且多样化的操作，已经构建了具有复杂形态的各种交联的嵌段共聚物纳米组装体，表现出对溶剂转换或外部刺激的优异结构稳定性。这篇综述的目的是总结通过RAFT介导的PISA工艺获得的稳定嵌段共聚物纳米组件的当前交联方法及其潜在应用。
