摘　　要：以纳米二氧化钛(TiO_2)和聚3-己基噻吩(P3HT)为原料,氯仿为溶剂,制备了TiO_2/P3HT纳米复合微粒。采用透射电镜(TEM)、X射线衍射(XRD)、X射线光电子能谱(XPS)、紫外-可见光漫反射光谱(UV-Vis DRS)等方法对复合微粒的结构和性能进行表征和分析。结果表明,通过P3HT修饰后的TiO_2/P3HT与纯TiO_2相比,晶型、粒径和形貌基本没有发生改变,平均粒径22nm;纳米TiO_2/P3HT比纯TiO_2在可见光区的光吸收能力增强,当TiO_2∶P3HT摩尔配合比为30∶1时,在波长508nm,TiO_2/P3HT的吸光度达到1.0123,而纯TiO_2的吸光度为0.10824。TiO2/P3 HT nanocomposites were prepared by blending TiO2 nanoparticles and P3 HT in chloroform solution.The structure and properties of composite particles were investigated by TEM,XRD,XPS and UV-Vis DRS.The results showed that the crystal shape,particle size and morphology of TiO2/P3 HT did not change comparing TiO2.DRS spectra showed that the absorption of TiO2/P3 HT nanocomposites increased in the visible region compared to TiO2.With the conditions that the molar ratio of TiO2 to P3HT was 30∶1,the wavelength of 508 nm,and the absorbance for TiO2/P3 HT was 1.0123 while 0.10824 for the the pure TiO2.
