Interfacial RAFT miniemulsion polymerisation - architectures from an interface

Tuesday, 9 June 2015

Directing polymerisation from a liquid-liquid interface is an emergent field delivering new insights into polymerisation mechanisms, while creating interesting and novel poly­mer architectures.

The investigations have led to a new class of interfacially active macro-RAFT agents.

A review by Australian researchers aims to explore how reversible addition-fragmentation chain-transfer (RAFT) polymerisation has been utilised in miniemulsion to perform controlled polymerisations at the biphasic liquid-liquid interface.

Producing capsule-like architectures

Highlighted herein are the initial investigations that led to a new class of interfacially active macro-RAFT agents. These are capable of stabilising emulsions, directing polymer growth from that interface, and subsequently producing capsule-like architectures. A comprehensive description is provided concerning the various macro-RAFT agents employed and the importance of performing this under miniemulsion conditions to obtain either nanoparticles, nanocapsules, and/or core–shell morphologies. Finally, a focus on exciting applications of such systems for the production of nanomaterials including delivery vehicles with stimuli-responsive properties is presented.

The study is published in: Macromolecular Chemistry and Physics.
