| Abstract: | Janus particulate emulsifiers integrate the amphiphilic performance of molecular surfactants and the Pickering effect of homogeneous particles, which are highly effective to stabilize emulsified systems. A new tool is thus provided to manipulate and functionalize interfaces, and to deliver functional materials toward interfaces. Relevant developments along with the Janus particulate emulsifier as a tool and soft matter interfacial engineering provide new opportunities for the interdisciplinary fusion of materials science with multiple fields. Composition, size, and microstructure are the key to fine-tuning the Janus granular emulsifier. The large-scale preparation of magnetically responsive Janus particles has been achieved, and it has shown advantages in the advanced treatment of the emulsification system. In recent years, the polymer single-chain nanoparticles and functional composite colloids have enriched the Janus material family, which are attractive in engineering micro-scale objects. Janus emulsifiers at multiple-length scales serve as a powerful tool to solve interfacial engineering problems. |
