| 摘 要： | 本文报道电化学沉积在光滑铂电极表面上聚吡咯 (PPy)膜的拉曼光谱。研究结果表明 :聚吡咯膜的掺杂程度在其生长过程中不断增加。因此 ,PPy膜的拉曼光谱特性对膜厚具有很强的依赖性。电化学分析结果也证明了这一发现。具有已知厚度的PPy膜的掺杂程度依赖于支持电解质的性质。

| Abstract: | As grown thin polypyrrole (PPy) films with different thickness electrochemically deposited on flat platinum electrode surfaces have been studied by Raman spectroscopy It is found that the overall features of the Raman spectra of PPy films depend strongly on film thickness, mainly due to the doping level increase during film growth process Electrochemical examinations also have confirmed this discovery The doping level of PPy film with a given thickness also depends on the property of supporting electrolyte |
