Abstract: Disclosed is a method for synthesizing antioxidant materials based on transition metal dichalcogenide (TMD) compounds and a technology of preparing a composition using the same. The monolayer TMDs functionalized with an amphiphilic block polymer compound and which is stably dispersed in an aqueous solution are prepared by two methods. The thus prepared monolayer TMDs were proven to exhibit excellent and sustained antioxidant effects and excellent stability to light and heat.

Abstract: The present invention relates to self-assembly type Janus microparticles and a preparation method therefor. The present invention can be used for preparing Janus microparticles in which a degree of phase separation is precisely controlled, for realizing stable interfacial orientation by selectively coating only one side of particles with a metal oxide, and for mass-producing Janus microparticles which have a degree of phase separation precisely controlled and exhibit extreme amphiphilicity in an anisotropic structure. Therefore, the Janus microparticles and the preparation method therefor according to the present invention can be widely used in various fields, thus contributing to industrial development.
