二氧化钛/聚乙烯吡咯烷酮纳米复合薄膜的制备与表征

Preparation and Characterization of TiO_2/PVP Nanocomposite Thin Films

采用溶胶-凝胶法(so1 gel)制备了TiO2/聚乙烯吡咯烷酮(PVP)有机 无机纳米复合薄膜.采用扫描电子显微镜、接触角测定仪、红外光谱仪、紫外 可见吸收光谱仪和静 动摩擦系数测定仪对所制备的TiO2/PVP纳米复合薄膜进行了结构表征和性能研究.结果表明:所制备的TiO2/PVP纳米复合薄膜表面平整光滑、无裂纹、具有一定的疏水性、良好的透明性、防紫外线性能和减摩抗磨性能.

Naonocomposite thin films of TiO2/PVP have been prepared by the solgel process. The TiO2 was obtained by the hydrolysis of titanium nbutoxide(TNBT) under the catalysis of HCl. Scanning electron microscopy, contact angel measurement apparatus, FTIR, UVVIS and dynamicstatic coefficient process measurement apparatus were applied to the study of the structure and properties of the films.
