摘要/Abstract

摘要： 通过控制四氯化钛(TiCl₄)的水解速度, 制备出水杨酸(SA)原位表面修饰的TiO₂纳米颗粒(TiO₂/SA). 通过X射线衍射仪(XRD), 高分辨透射电子显微镜(HRTEM), 红外光谱仪(FT-IR), 热分析(TG-DTA)和X射线光电子能谱(XPS)等实验分析手段对表面改性前后的TiO2纳米颗粒进行了表征, 结果表明表面修饰水杨酸的TiO₂纳米颗粒在乙醇中有良好的分散性, 将TiO₂/SA加入到光信息存储薄膜材料(PVA/AM)中, 能大大提高材料的衍射效率, 降低布拉格偏移.

Abstract: 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).

Key words: TiO₂ nanoparticles, salicylic acid, surface-modified
