Abstract

Polymer brush-grafted particles (i.e., hairy particles) capable of undergoing direct, especially reversible, phase transfer from one liquid phase to another immiscible liquid phase in response to environmental changes have received growing interest due to their great potential in a wide variety of applications. This article is intended to review recent exciting advances in stimuli-triggered phase transfer of hairy particles in liquid-liquid biphasic systems. We start with a discussion of the mechanism of particle transfer across a liquid-liquid interface and progress to the synthesis of polymer brushes grafted on particles and the transfer of hairy particles between two immiscible liquid phases induced by various external stimuli, including temperature, pH, ionic strength, light, and solvents. The applications of thermally triggered phase transfer of hairy particles in catalysis (thermoregulated phase transfer catalysis) are discussed, followed by a summary and our perspective on future development.
