SYNTHESIS, CAPPING, AND DISPERSION OF TIO2 NANOCRYSTALS

The preparation of monodispersed TiO2 nanocrystals with nanocrystal size between 1-30 nm is described herein. These TiO2 nanocrystals are used to prepare dispersions into solvents, formulation into monomers, oligomers, and polymers, and nanocomposites from the resulting formulations. Dispersions of nanocrystals can be formed in various solvents at high loading, high transmittance, and low viscosity. Formulations incorporating these nanocrystals and a matrix material are highly stable, where the resulting nanocomposites have high refractive index and are optically transparent in the visible wavelengths, with very little or no scattering. 本文描述了纳米晶体尺寸在1nm至30nm之间的单分散TiO2纳米晶体的制备。这些TiO2纳米晶体用于制备溶剂中的分散体，配制成单体、低聚物和聚合物的配方，以及由所得配方制成的纳米复合材料。纳米晶体的分散体可在各种溶剂中以高负载、高透射率和低粘度形成。掺入了这些纳米晶体和基质材料的配方是高度稳定的，其中所得的纳米复合材料具有高折射率，并且在可见光波长下是光学透明的，几乎没有散射或没有散射。
