The present specification describes a method for manufacturing porous inorganic particles and a light-reflecting composition comprising porous inorganic particles. According to an embodiment of the present disclosure it is possible to provide a method for manufacturing porous inorganic particles capable of selective transmission or scattering of light having a specific wavelength range by controlling pore size and shell thickness.

Method for manufacturing porous inorganic particle and light-reflecting composition comprising porous inorganic particle

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.
