摘要：

The surface of TiO2 nanoparticles prepared by controlling hydrolysis of a titanium tetrachloride (TiCl4) precursor was modified with salicylic acid (SA). The prepared samples were characterized by X-ray diffraction (XRD), high resolution transmission electron microscope (HRTEM) and Fourier transformation infrared spectrometry (FT-IR). The chemical feature and state of TiO2/SA were analyzed by X-ray photoelectron spectroscope (XPS). From the experiments, the surface-modified TiO2 nanoparticles with SA have excellent dispersibility in ethanol. As functionalized inorganic fillers, TiO2/SA nanoparticles increase the diffraction efficiency and reduce the Bragg mismatch of the photopolymer film, which have a great applied prospect in holographic data storage (HDS).
