Synthesis of AB_n-type colloidal molecules by polymerization-induced particle-assembly (PIPA)

Abstract

Using isotropic diblock copolymer spheres, polymerization-induced particle-assembly directly produces colloidal molecules.

RAFT-mediated polymerization-induced self-assembly (RAFT-PISA): current status and future directions

“…In 2020, Yuan, Yang and co-workers demonstrated the preparation of rarely achieved colloidal molecules (CMs) by seeded dispersion polymerization of HPMA with PDMA- b -PBzMA nanoparticles as seeds. 33 First, the PDMA- b -PBzMA colloidal atoms (CAs) were synthesized via PISA in ethanol, it was then dialyzed against water (pH ∼ 2) to remove ethanol. In the growth of the third block, they found that phase separation between PHPMA and PBzMA occurs as the DP of PHPMA increases.…”

Lateral growth of cylinders

“…The fusion and assembly of particles is an emerging method to fabricate nanomaterials with precisely controlled anisotropy or highly ordered structures 29 – 33 . For instance, Yuan and coworkers fabricated AB n -type colloidal particles by polymerization-induced particle-assembly using a linear ABC triblock terpolymer, and the number of n could be controlled between 2 and 6 by tuning the volume ratio of different blocks 29 . O’Reilly et al investigated the polymerization-induced fusion behaviors of polymersomes 33 .…”

Synthesis of Biologically Decomposable Terpolymer Nanocapsules and Higher‐Order Nanoassemblies Using RCMP‐PISA

“…Yuan et al. [ 19 ] also obtained higher‐order structures using polymerization‐induced particle self‐assembly (PIPA). In our system, as the C segment grows, the generated micelles started to aggregate and formed an MCM (structure (e) in Scheme 3) at 22 DPs of PGMA (C segment) (monomer conversion = 26%).…”

“…[ 3,6,17 ] PISA has also been used for synthesizing ABC terpolymer‐based higher‐order self‐assemblies such as multicompartment micelles. [ 17–20 ]…”
