Synthesis of Organic–Inorganic Hybrid Sols Using Trifunctional Organoalkoxysilanes for Dispersion Agents
Abstract:We investigated the properties of synthetically produced organic–inorganic hybrid coatings by a sol–gel process. The properties of organic–inorganic hybrid materials arise from the synergism between the properties of the individual components. One of the typical way to synthesize the organic–inorganic hybrid materials is to use silica and silanes. A colloidal silica sol was used as an inorganic material. Methyltrimethoxysilane and phenyltrimethoxysilane were used as the trifunctional organoalkoxysilanes. Hybrid sols of colloidal silica and silanes were synthesized as a function of reaction time and methyltrimethoxysilane/phenyltrimethoxysilane ratio by a sol–gel process. Physical properties of sol solutions such as stability, viscosity, and transmittance were investigated. The surface roughness and surface free energy of the coatings were also measured.
