Janus particles, which combine the amphiphilicity of molecular surfactants and the Pickering effect of homogeneous particles, have gained significant attention in recent years. In this review, synthesis methods, stabilization mechanism and the applications in interfacial engineering of Janus particles are discussed.

Abstract

Janus particles with different compositions and properties segmented to different regions on the surface of one objector provide more opportunities for interfacial engineering. As a novel interfacial active material, Janus particles integrate the amphiphilic properties of molecular surfactants and the Pickering effect of homogeneous particles. In this research, the outstanding properties of Janus particles on various interfaces are examined from both theoretical and practical perspectives, and the advantages of Janus particles over molecular surfactants and homogeneous particle surfactants are analyzed. We believe that Janus particles are ideal tools for interface regulation and functionalization in the future.

There are more chances for interfacial engineering when Janus particles with different properties and compositions are spread out on the surface of a single objector. Janus particles are a new type of interfacial active material that combines the amphiphilic properties of molecular surfactants with the Pickering effect of uniform particles.
