TiO₂ nanoparticles with surface hydroxyl groups are treated by trimethoxysilane (CH₃O)₃Si(CH₂)₃O(CH₂CH₂O)_6-9CH₃ and a inorganic core/organic shell hybridmaterials, which shows itself a yellow viscous fluid, is obtained. We call it solvent-free TiO₂ nanofliuds. Transmission electron microscopy (TEM), Fourier transform infrared spectrum (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and rheometer are adopted to characterize the product. As a result, the content of TiO₂ nanoparticles in the nanofliuds is about 5.5wt%, the functionalized TiO₂ nanoparticles possess better dispersion, very low viscosity and an obvious liquid-like behavior at room temperature in absence of solvent.
