Abstract
Silica nanoparticles occupy a prominent position in scientific research, because of their easy preparation and their wide uses in various industrial applications. Many researchers have focused on synthetic approach to get well controlled monodispersed particles and their surface modification with functionalities that can be applicable to composites with organic polymers. In this study, organosilanepolyol was employed as a modifier instead of alkoxysilane. Silica nanoparticles (SNPs) were synthesized by Stöber’s method and modified using phenylsilanetriol as a presentative modifier in a range from 0.1 to 10 wt % based on the silica used. The characterizations of all modified particles including particle sizes, surface morphologies, hydrophobicity, etc. were systemically carried out using various analytical tools (SEM, TEM, DLS, BET, etc.). In this seminar, recent results obtained from the surface modification approach to silica and some inorganic oxide particles will be presented in details.
