Stimuli-responsive emulsions: Recent advances and potential applications

doi:10.1016/j.cjche.2021.11.002

Abstract

Abstract: Responsive emulsions are the emulsions that can be reversibly switched on-demand between “stable” and “unstable” by environmental stimulus or trigger, which allows a simple and effective adjustment approach to achieve emulsification and demulsification. In recent years, stimuli-responsive emulsions acting as smart soft material are received considerable attention with the advantages of simple manipulation, good reversibility, low cost, easy treatment, and little effect on the system. In this paper, the recent research progress of emulsions that can respond to external stimuli, including pH, light, magnetic field, CO₂/N₂ and dual responsive are reviewed. Also, the potential applications based on responsive emulsion are discussed, such as catalytic reactions, heavy oil recovery, polymer particles synthesis and optical sensor, aiming to summarize the latest achievements and put forward the possible development trends of responsive emulsions.

Key words: Stimuli-responsive, Emulsions, Switchable surfactants, Interface
