The definition and formation mechanism of Pickering emulsions are reviewed, and their applications in the preparation of polymer nanocomposites are introduced. This study will focus on the use of methyl methacrylate and butyl methacrylate as monomers, and polyethylene glycol as a surfactant to construct Pickering emulsions, and we will prepare core-shell structured polymer inorganic nanoparticle composite microspheres through free radical polymerization, and we will explore the influence of factors such as formulation, surfactant dose and polymerization reaction conditions on the morphology and size of microspheres. At the same time, the surface properties and application performance of composite microspheres were preliminarily studied, and their potential application value as drug carriers and catalysts was determined.精品文档---下载后可任意编辑Keywords: Pickering emulsion; core-shell structure; polymer inorganic nanoparticles; composite microspheres; surface properties; application performance
