Self-assembly of nanoparticles employing polymerization-induced phase separation

Journal of Colloid and Interface Science, 2014
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.

ROMPISA: Ring-Opening Metathesis Polymerization-Induced Self-Assembly

ACS Macro Letters, 2017
Herein we report a polymerization-induced self-assembly (PISA) process with ring-opening metathesis polymerization (ROMP). We utilize a peptide-based norbornenyl monomer as a hydrophobic unit to provide a range of nanostructures at room temperature yet at high solids concentrations of 20 wt % in combination with an oligoethylene glycol based ...

Gradient Polymerization–Induced Self‐Assembly: A One‐Step Approach

Macromolecular Rapid Communications, 2019
AbstractIn this work, the authors report a novel single‐step, one‐pot process for the synthesis of self‐assembled nanoparticles using a polymerization‐induced self‐assembly (PISA) mechanism. In contrast to conventional approaches employing a pre‐formed macromolecular stabilizer, the disparate reactivities between two monomers, oligo(ethylene glycol ...

In Situ Cross-Linking of Vesicles in Polymerization-Induced Self-Assembly

ACS Macro Letters, 2016
In situ cross-linking of nano-objects with controllable morphologies in polymerization-induced self-assembly (PISA) has been a challenge because cross-linking lowers chain mobility and hence inhibits morphology transition. Herein, we propose a novel strategy that allows in situ cross-linking of vesicles in PISA in an aqueous dispersion polymerization ...

Precise Mesoscopic Model Providing Insights into Polymerization-Induced Self-Assembly

Langmuir, 2020
Self-assembly of copolymer is an important approach to obtain multifarious nanostructures. Polymerization-induced self-assembly (PISA) is a recently developed and powerful copolymer self-assembly strategy. However, some researchers have reported a different morphology prepared by PISA and the traditional copolymer self-assembly using the same copolymer
