【 摘 要 】

Monodisperse organic functionalized silica micro/nano spheres have been extensive research due to their special structural features. In this study, the Monodisperse organic functionalized silica micro/nano spheres were prepared by one-step hydrolysis condensation reaction of organosilane including TCPTES, MPTES, CTES, CPTES, UPTES in microemulsion system. It was showed that it was no particles from UPTES in the presence of SDS, and organic silica spheres prepared with CTES and CPTES had uniform particle size and monodispersity. However, organic silica spheres with poor disperse can be obtained from UPTES in the presence of CTAB, due to the physical adsorption between charges. In the contrast with SDS system, other organic silica spheres had poor disperse and nonuniform particle size.
