제목 The fabrication of monodisperse polymeric microparticles coated with silica through droplet based microfluidic system
초록 This study presents a microfluidic method for preparation of organic−inorganic hybridmicrospheres with poly(Dodecanediolo Dimethacrylate-co-Trimethoxysillyl propylmethacrylate) as the core and silica nanoparticles as the shell. In this process, the monodisperse microspheres of P(DDMA-co-MPS) were first synthesized via microfluidic approach of droplet generation combined within situ photopolymerization, and nanosilica particles gradually grew on the surface of microsphere via hydrolysis and condensation of tetraethoxysilane in basic ammonium hydroxide medium without additional surface treatment. The morphology, composition, and crystalline structure of the hybrid microspheres were confirmed by scanning electron microscopy, transmission electron microscopy, etc. The results indicated that the shell of the complex microspheres consists of SiO2 microspheres with about 60 nm. Finally, we suggest the coating mechanism of SiO2 nanoparticles on the polymeric microsphere.
