摘　　要：以巯基乙酸掺杂的聚苯胺纳米线为硫源和基底,通过水热反应成功制备了CdS纳米晶负载聚苯胺纳米线.所制备的CdS纳米晶负载聚苯胺纳米线的形貌、晶体结构、元素价态以及光电性质分别利用透射电镜(TEM)、X射线衍射(XRD)、X射线光电子能谱(XPS)、紫外⁃可见吸收光谱、表面光电压谱(SPS)进行了表征.5~10 nm的CdS纳米晶随机且均匀地负载在PANI纳米线的表面.表面光电压响应显示,所制备的CdS纳米晶负载聚苯胺纳米线可以作为p-n结以及光电功能材料来使用.By using thioglycolic acid(TGA)doped polyaniline(PANI)nanowires as sulfur source and matrix,CdS nanocrystals(NCs)decorated PANI nanowires were prepared via hydrothermal reaction.The morphology,crystal structure,valence state and photoelectric properties of the prepared CdS NCs decorated PANI nanowires were characterized by transmission electron microscopy(TEM),X⁃ray diffraction(XRD),X⁃ray photoelectron spectrum(XPS),UV⁃vis spectra and surface photovoltage spectroscopy(SPS).The CdS NCs with a size in the range of 5⁃10 nm were uniformly decorated on the surface of PANI nanowires.The photovoltage response measurement demonstrates the sprayed CdS NCs decorated PANI nanowires film can be used as p⁃n junction and photoelectric functional materials.
