Cross-linking approaches for block copolymer nano-assemblies via RAFT-mediated polymerization-induced self-assembly

Author affiliations

Abstract

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.
