Synthesis of Janus composite particles by the template of dumbbell-like silica/polystyrene
چکیده انگلیسی

Janus particles possess promising performances. It is challenging to develop new methods to control composition and microstructure of the particles. In this report, we describe a general template synthesis of several non-spherical Janus composite particles by the template of dumbbell-like silica/polystyrene (PS) Janus particles. Both PS and silica can be modified to introduce desired functional groups respectively, or induce crystallization of other materials on the particle surface. Especially, by favorable growth of materials within the sulfonated PS gel forming the core–shell structure at the polymer part, several new Janus hollow particles are obtained after removal of the PS core.


► We synthesize Janus composite particles by template.
► The part of sulfonated polystyrene can induce a favorable formation of materials.
► Janus hollow particles are obtained after the removal of polystyrene core.
► The silica part can also induce a favorable growth of materials by using silanes.
