| 摘 要： | 通过溶液共混方法制备了聚苯胺（PANI）-富勒烯复合膜, 并用IR、XRD、UV-Vis等技术对其进行表征.红外光谱表明聚苯胺与C60之间存在相互作用且表现为掺杂态聚苯胺红外谱图样.X射线衍射表明复合体材料的结晶性能增强.光致发光谱表明聚苯胺与C60分子之间存在有效光诱导电荷分离现象.光电响应实验表明复合体薄膜的光吸收增强, 光电流增大, 说明聚苯胺-富勒烯复合膜受光照射后发生了光诱导电荷分离现象, C60掺杂聚苯胺有助于改善光伏特性.

| Abstract: | Polyaniline (PANI)-C60 composites film was prepared by liquid-state mixture of PANI and C60 solutions. The interaction between polyaniline emerald base and C60 were investigated and explained according to the results of FTIR spectroscopy. The improvement of crystallinity of PANI-C60 composites were evaluated by using X-ray diffraction spectra (XRD). The mechanism of charge transport in these composites was also studied. The photoconductivity of PANI-C60 composites film was enhanced markedly and photoluminescence spectra (PL) intensity decreased greatly, which take the photoinduced charge transfer between PANI and C60 into consideration. |
