ENCAPSULATION OF ACTIVE COMPONENTS INTO HOLLOW SILICA NANOSPHERES BY ONE-POT SYNTHESIS IN MICROEMULSION

摘要

The present invention relates to a method for preparing a semiconductor device, comprising: preparing a reaction solution comprising a silica precursor; Forming a reverse micelle in which a surfactant is added to the solution to form reverse micelles, a W / O micelle formation step in which an acidic aqueous solution is added to the reverse micelle-formed solution, and the mixture is stirred to introduce an acidic aqueous solution into the reverse micelle hollow ; And a step of synthesizing a silica hollow body in which a silica hollow body is formed by sol-gel reaction of the added silica precursor and an acidic aqueous solution to thereby obtain a heterogeneous material and silica synthesis, To a method of forming a co-fusible silica hollow body.
