Nanoengineering with RAFT polymers: from nanocomposite design to applications

Abstract

Reversible addition–fragmentation chain-transfer (RAFT) polymerization is a powerful tool for the precise formation of macromolecular building blocks that can be used for the construction of well-defined nanocomposites.

Proton conductivity dependence on the surface polymer thickness of core–shell type nanoparticles in a proton exchange membrane

“…19,20 The core-shell type nanoparticles that composed of silica nanoparticles as a core material and poly(acrylic acid)-block-polystyrene (PAA-b-PS) as shell polymer was prepared by reversible addition-fragmentation chain transfer polymerization with particles method (RAFT PwP). [21][22][23][24] The RAFT PwP is an in-situ polymer coating method on the surface of core nanoparticles in which RAFT polymerization is performed in the coexistence of core particles and monomers. Based on the above in-situ polymer-coating method, it can be said that we can also fabricate the core-shell type nanoparticles using the free radical polymerization with particles method.…”

RAFT-Based Polymers for Click Reactions

“…This choice is conditioned by the high versatility of RAFT-based polymers from the standpoint of modification opportunities for both chain-end groups and by low sensitivity of the RAFT process to the chemical nature of the functional groups. The interest to the combination of RAFT polymerization and click chemistry is still growing and new publications appear almost every week [ 229 , 230 , 231 , 232 , 233 ].…”

Novel Strategy for the Synthesis of Polymer/Pigment Hybrid Latex via Sulfur-Free RAFT-Mediated Emulsion Polymerization

“…Organic/inorganic nanohybrid materials are cited as one of the most promising developments in the field of materials science, which take advantage of the combination of organic and inorganic components at the nanoscale. In the past few decades, colloidal polymers/inorganic nanoparticle (NP) hybrid materials through reversible addition–fragmentation chain transfer (RAFT) polymerization have attracted widespread attention because of their controllable size, morphology, and the macromolecular architecture of the polymers, and a series of powerful strategies have been established to the design and synthesis of core–shell nanohybrid materials for each specific application scenario. , Moreover, these RAFT polymer/NP hybrid materials showed promising applications in many fields, including life science (bioimaging, drug delivery, or cancer therapy), − energy conversion (such as solar cells), − catalysis, − and paints and coatings − (such as digital ink-jet printing of textile). , …”
