Sol-gel polymerization was used to prepare stable nano-TiO 2 / organic polymer modified hybrid materials. The effects of different reaction methods on the particle shape, solution stability and optical refractive index of the hybrid material were investigated. IR and TEM analyzes show that the material is composed of Si - O - Ti bonds and surface organic polymers, and has a nano - sized structure. The hybrid material has a good stability in a mixed solvent composed of toluene / butanol
