▎ 摘  要

A novel graphene oxide/titanium dioxide (GO/TiO2) solvent-free nanofluid was firstly synthesized by employing GO, which was in-situ deposited by TiO2 as the core and (3-Glycidyloxypropyl) trime thoxysilane (KH560) and polyetheramine-M2070 as the shell. The morphology and structure of GO/TiO2 nanofluid were verified by Transmission electron microscopy (TEM), X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and UV-vis absorption spectra. These studies confirmed that TiO2 has been deposited onto GO with good dispersion, and the organic shell has been grafted onto the core successfully. Thermo gravimetric analysis (TGA) and viscosity analysis indicated that this nanoparticle hybrid material presented a liquid state without solvent at room temperature, and has great fluidity and thermal stability. The solubility investigation of GO/TiO2 nanofluid revealed its excellent amphiphilicity and the potential as the functional nanocomposites.
