Abstract
Organic-inorganic hybrid silica particles spheres with controllable size from 0.6 µm to 4.2µm and prepared in water using a one-pot synthesis. In this study, organic-inorganic hybrid silica particles were synthesized using self-emulsion process with various silane monomers. Phenyltrimethoxysilane (PTMS) based particles were controlled by changing the reaction temperature, the molar ratio of monomer, catalyst and stirring rate. Through this method, a highly yield of mono-dispersed hybrid particles was obtained under the basic conditions. There are several major advantages in our method as follows. First, The fabrication of silica particles having a highly mono-dispersity was tried by self-hydrolysis. Second, it is a considerably simple mechanism for preparing particles loading a lot of organic materials. The best of our methods is possible that the particles can be large quantity production. In addition, we approached to find particles which do not dissolve in organic solvents. It was by controlling the sintering conditions and preparing composite particles. Composite particles with Vinyltrimethoxysilane (VTMS), 3-mercaptopropyl-trmethoxysilane (MPTMS), Tetraethylorthosilicate (TEOS) were controlled by changing the reaction temperature. Organic-inorganic hybrid silica particles are expected to be used in diverse applications including composite materials, catalysis, delivery systems and biomedical industries.
