Abstract

Abstract: Oleic acid modified TiO₂ nanoparticles were dispersed into transformer oil to prepare TiO₂ nanoparticles modified transformer oil by ultrasonic treatment. The effect of surface modification on the dispersibility of TiO₂ nanoparticles in the oil was investigated. The morphology, structure and surface modification state of TiO₂ nanoparticles were characterized by X-ray powder diffraction (XRD), transmission electron microscope (TEM), Fourier transform infrared spectra (FT-IR) and thermogravimetric method (TG). The results show that oleic acid is bound on the surface of TiO₂ nanoparticles by bidentate coordination, and an effective modification layer is formed. With the increasing of modifying agent dosage, although the coordination pattern of oleic acid on the nanoparticle surface remains, the mass fraction of chemisorbed oleic acid obviously increases. The dispersibility and stability of TiO2 nanoparticles in the oil is dramatically improved. When the molar ratio of titanium salt to oleic acid is 1:24, TiO₂ nanoparticles can be well dispersed in the transformer oil and keep transparent after aged for 30 d at room temperature.
