Reprint of: Self-assembly of nanoparticles employing polymerization-induced phase separation

Journal of Colloid and Interface Science, 2015
Nanoparticles (NPs) may be homogeneously dispersed in the precursors of a polymer (reactive solvent) by an adequate selection of their stabilizing ligands. However, the dispersion can become metastable or unstable in the course of polymerization.

The Effect of Hydrophile Topology in RAFT‐Mediated Polymerization‐Induced Self‐Assembly

Angewandte Chemie, 2016
AbstractPolymerization‐induced self‐assembly (PISA) was employed to compare the self‐assembly of different amphiphilic block copolymers. They were obtained by emulsion polymerization of styrene in water using hydrophilic poly(N‐acryloylmorpholine) (PNAM)‐based macromolecular RAFT agents with different structures.

Polymerization-Induced Self-Assembly Promoted by Liquid–Liquid Phase Separation

ACS Macro Letters, 2019
Polymerization-induced self-assembly (PISA) is a powerful method for the synthesis of polymeric kinetically frozen core nanoparticles. However, the PISA synthesis of biologically important polymeric fluidic materials is unexplored. Herein we present a liquid-liquid phase separation mode PISA.

An insight into polymerization-induced self-assembly by dissipative particle dynamics simulation

Soft Matter, 2016
Polymerization-induced self-assembly is a one-pot route to produce concentrated dispersions of block copolymer nano-objects. Herein, dissipative particle dynamics simulations with a reaction model were employed to investigate the behaviors of polymerization-induced self-assembly.

Aqueous-Phase Ring-Opening Metathesis Polymerization-Induced Self-Assembly

ACS Macro Letters, 2018
We report aqueous-phase Ring-Opening Metathesis Polymerization-Induced Self-Assembly (ROMPISA) for forming well-defined micellar polymer nanoparticles at room temperature and high solids concentration (20 w/w%). This is achieved with a new polymerization initiator, in the form of a water-soluble cationic Hoveyda-Grubbs second generation catalyst.
