The Particle Size Control of Organic-Inorganic Hybrid Silica by Surfactant-Mediated Assembly of Silsesquioxane

Abstract:

Organic-inorganic hybrid silica were prepared via surfactant-mediated assembly of 1,2-bis (triethoxysilyl) ethane in a modified stöber process. Factors that affect the size of silica particles were investigated in detail. It is found that larger silica spheres are obtained under lower surfactant concentration, higher ammonia concentration and lower synthesis temperature; The size and dispersibility of silica particles also depend strongly on the amount of water in the mixture.
