Synthesis of high refractive index nanocomposite by solution blending method can control the particle size distribution and surface properties of nanoparticles, and improve the dispersion of nanoparticles in organic matrices. TiO2 nanoparticles are widely used in areas such as optical devices, sensors and photocatalysis because of their excellent photoelectric performance. The homogeneous dispersion of TiO2 nanoparticles in the organic solvent is an important prerequisite for preparing high refractive index nanocomposites by solution blending method. In this paper, three kinds of silane coupling agents (SCAs) with different carbon functionalities were used to modify the surface of TiO2 nanoparticles, which can be dispersed in three organic solvents with different polarities to obtain a transparent and stable dispersion. Results indicate that the median particle size (D50) of TiO2 nanoparticles in heptane, butyl acetate and 1-butanol are 13.5, 19.6 and 22.1 nm, respectively, and the distribution coefficients (PDI) are 0.038, 0.231 and 0.171, respectively. Dynamic laser scattering (DLS) measurements and transmission electron microscopical (TEM) observation indicate that the TiO2 nanoparticles are dispersed on a primary particle size level. Turbiscan stability analyzer analysis demonstrates that TiO2 dispersions with the same mass fraction of TiO2 nanoparticles have different dispersion stability, indicating that the best compatibility is hexadecyltrimethoxysilane and heptane, and the dispersion has high dispersibility and good stability, followed by 3-(methacryloyloxy)propyltrimethylsilane with butyl acetate. This study indicates that the properties of the carbon functionalities of the SCAs are vital to the dispersion state of TiO2 nanoparticles in organic solvents, and provides a new idea for the preparation of dispersion with high dispersibility and stability.
