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。 This article reports the Raman spectra of PPy films deposited on the surface of a smooth platinum electrode by electrochemical deposition. The results show that the doping degree of polypyrrole film increases continuously during its growth. Therefore, the Raman spectrum of the PPy film has a strong dependence on the film thickness. Electrochemical analysis also proved this finding. The degree of doping of a PPy film of known thickness depends on the nature of the supporting electrolyte.
