Abstract:

Surfactants are a very important class of additives in industrial field. However, the issues of separation and recycling are extremely challenging. Janus particle, with asymmetric property or architecture, is a novel type of interfacial active material. Janus particle not only exhibits interfacial activity which is similar to surfactant molecule, but also possesses significantly higher mass than that of surfactants, which might be utilized to overcome the before mentioned problems and might be applied as a candidate for surfactants. The methods for preparation of Janus particles were reviewed, such as template, phase separation, emulsion polymerization, self-assembly, wet chemistry and microfluidic methods. The development directions of Janus particles in the future were also prospected.

Key words: Janus, micro/nanoparticles, preparation
