Self-assembly type janus microparticle and preparation method therefor

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.
