Tailoring the Multicompartment Nanostructures of Fluoro-Containing ABC Triblock Terpolymer Assemblies via Polymerization-Induced Self-Assembly

Abstract

Polymer self-assembly has been one of the most important strategies for preparation of multicompartment micelles (MCMs). However, the traditional self-assembly techniques are constrained by limited common solvent, complex kinetic factors, low solids content, etc. Polymerization-induced self-assembly (PISA) is a novel technique for preparation of polymer assemblies at high solids content and has been exploited to produce MCMs. Nevertheless, the morphology evolution of the MCMs obtained through PISA has not yet been well understood. Herein, we study the compartmentalization behaviors of a series of MCMs constituted by poly(N,N-dimethylaminoethyl methacrylate)-b-poly(benzyl methacrylate)-b-poly(2-perfluorohexylethyl methacrylate) (PDMA-b-PBzMA-b-PFHEMA) triblock terpolymers, which were synthesized by seeded reversible addition–fragmentation chain transfer (RAFT) dispersion polymerization of FHEMA using PDMA-b-PBzMA micelles, wormlike micelles, or vesicles as the seeds. Because of the strong incompatibility b...
