摘要： 显微共焦拉曼技术被用来研究电化学合成的聚苯胺（PANI）膜. 研究结果表明：在不同的激发光聚焦深度，聚苯胺膜的拉曼光谱有明显变化.从而反映出聚苯胺膜的掺杂程度在膜生长过程中随膜厚度的增长而增加. 并由X射线电子能谱（XPS）和紫外吸收光谱（UV）分析证实.

关键词: 拉曼光谱, 聚苯胺, 掺杂程度, 膜厚度

Abstract: The doped polyaniline (PANI) films with different thickness electrodeposited on flat platinum electrode surface have been studied by confocal Raman spectroscopy. It was found that the overall features of the Raman spectra depend strongly on the confocal depth. Therefore, it can be deduced that the doping level of the PANI film increases with film thickness during film growing process. X-ray photoelectron spectroscopic (XPS) analysis and ultraviolet-visible (UV) absorption spectrum results also confirmed this idea.
