| 제목 | Synthesis of hollow PMMA particles by SiO2-stabilized Pickering emulsion polymerization |
| 초록 | Hollow polymer microspheres have attracted increasing attentions due to their wide applications, such as encapsulation for controlled release, catalysts, and adsorption materials for sound. The hybrid hollow spheres usually are fabricated by sol-gel process, liquid deposition, and layer by layer assembly. Recently, Pickering emulsion has been developed for the preparation of polymer microspheres. Instead of organic surfactants, fine, solid particles, such as silica, titania, ZnO and etc, are used to stabilize emulsions in the Pickering emulsion system. In this study, hollow PMMA microspheres were fabricated from Pickering emulsion stabilized by SiO2 nanoparticles and the morphology and chemical structure of the hybrid hollow microspheres were investigated. |
