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.

Abstract: A method for preparing porous inorganic particles is disclosed. The method includes the steps of: (a) preparing an emulsion comprising an inorganic precursor and a polar solvent; (b) adding an organic solvent to the emulsion of step (a) to swell emulsion particles; (c) mixing the swollen emulsion of step (b) with polymer particles having a positive charge on the surface thereof; (d) adding a surfactant to the mixture of step (c) and removing the organic solvent; (e) adding an initiator to the result of step (d) to polymerize the same; and (f) firing the result of step (e) to remove the polymer particles so as to form macropores.
