中文摘要：
通过电化学阳极氧化法在Ti片上制备了氧化钛（TiO2）纳米管阵列。用这种高度有序的阵列结构作为模板，利用电泳沉积的方法在模板表面沉积了一种有机半导体材料酞菁铜（CuPc），从而得到了CuPc／TiO2有机／无机纳米复合结构。通过场发射扫描电镜（FESEM），透射电镜（TEM）等手段对这种复合结构的表面形貌及结构进行了表征。能谱数据证实了复合结构中有机物的存在。此外，CuPc薄膜的形貌和结构可以通过改变电泳沉积参数（如沉积时间和电压）进行调控，从而得到相应的纳米晶、纳米线和微米线薄膜。用该复合薄膜作为载流子发生层制备的双层光导体的光导性能测试结果表明，与复合前的氧化钛薄膜相比，该复合薄膜的光敏性有明显的提高。
英文摘要：
Titania （TiO2） nanotube arrays were fabricated by anodic oxidation of Ti sheets in electrolyte solution. With the vertically-oriented arrays as templates, copper phthalocyanine （CuPc）, an organic semiconductor, was deposited on them using a facile electrophoretic deposition method, forming an organic/inorganic nanocomposite structure. The morphology and structure of TiO2 nanotube/CuPc films were studied by filed-emission scanning electron microscope （FESEM）, transmission electron microscope （TEM）. Energy dispersive X-ray microanalysis （EDX） data demonstrated the existence of the CuPc on TiOz nanoarray membranes. Moreover, the morphology and structure of the as-deposited CuPc films could be controlled by altering the electrophoretic deposition parameters, such as electrodeposition voltage and time. Photoconductivity of the photoreceptor from the nanocomposite film under illumination of full wave band light was investigated by using photoinduced xerographic discharge technique. The results indicated that the photoreceptor with the nanocomposite film showed a higher photosensitivity than that from original titania nanotube arrays.
