TiO2-C composite films are prepared by a sol-gel process.A soluble organic compound,salicylic acid, coupled with a quasi-crystallized benzene ring structure is served as carbon sources,resulting in a considerable uniform carbon network in nano-scale and developing novel properties.Using scanning electron microscope, transmission electron microscope, Raman spectrometer, Fourier transform infrared spectroscopy, differential thermal analysis and four-point probe, the structure,composition and the performance of the films are characterized and investigated.The results reveal that the carbon network consists of well-defined nano-graphites, which facilitate the conductivity of the film, leading to an excellent electrical resistance as low as ~ 10-3 Ω·cm.Furthermore, the TiO2 in the film perform as nano-particles also enhanced the mechanical and chemical properties of the composite films.
