In this study, we present the simple method of fabricating silica shell structured particle. It can be synthesized by using simple 2-step fabrication method. First step is generation of polymeric particle template which is functionalized silanol group for silica grafting. And second step is development of silica nano-particle by using sol-gel reaction. In the first step, we generate polymeric micro droplet by using microfluidic system. And then, these droplet was photo-polymerized by exposing UV irradiation. Through facile microfluidic system, we obtained highly mono-dispersed size and maintained very stable silanol group functionalized polymeric particle template. Subsequently, silica shell structure on surface of generated particles succeeded in conventional sol-gel reaction using tetraethylorthosilicate (TEOS) as precursor. In conclusion, we successfully fabricate monodisperse silica shell structured particle. |
