以聚氯乙烯（PVC）、氯化铝（AlCl 3）以及PVC和AlCl 3的混合物为掺杂剂，采用电子束沉积（EBD）法在硅和石英玻璃衬底上制备了聚苯胺（PANI）复合薄膜。采用傅里叶变换红外光谱、紫外-可见光谱、四探针法和原子力显微镜对聚苯胺复合膜的分子结构、形貌、光学和电学性能进行了研究。结果表明，EBD法制备的聚苯胺薄膜具有与原始粉末相似的分子结构。PVC在电子束辐照下脱氯化氢，但HCl未能质子化PANI的醌型网站在薄膜沉积过程中。AlCl 3掺杂的聚苯胺薄膜的表面电阻降低，并在复合膜中形成了双层结构。此外，AlCl 3促进了PVC的分解，提高了（AlCl 3，PVC）掺杂聚苯胺复合膜的表面电阻。Polym.工程索引，2013.© 2012年塑料工程师协会
Polyaniline (PANI) composite films were prepared on silicon and quartz glass substrates by electron beam deposition (EBD), using polyvinyl chloride (PVC), aluminum trichloride (AlCl3), and mixture of PVC and AlCl3 as dopants. Molecular structure, morphology, optical, and electrical properties of PANI composite films were investigated by Fourier transform infrared spectroscopy, UV–vis spectroscopy, four-probe method, and atomic force microscope. The results show that PANI film prepared by EBD has a similar molecular structure with initial powder. PVC is dehydrochlorinated under electron beam irradiation, but HCl fails to protonate the quinoid site of PANI during films deposition. AlCl3 doped in PANI films induces the decrease of surface resistance and the formation of a two-layered morphological structure in composite film. In addition, AlCl3 enhances the decomposition of PVC and increases the surface resistance of (AlCl3, PVC)-doped PANI composite film. POLYM. ENG. SCI., 2013. © 2012 Society of Plastics Engineers
