摘要: 提出了制备二维纳米有序有机导电聚合物膜的新方法--电化学组装法,应用该方法在电位脉冲的作用下使苯胺聚合到对-巯基苯胺修饰的金电极上,获得了致密、有序的对-巯基苯胺/聚苯胺(p-aminothiolphenol/polyaniline,PATP/PANI)导电寡聚物薄膜.用STM研究了Au(111)/PATP、Au(111)/PATP/PANI膜表面的二维有序性,用SERS谱表征了Au(粗糙表面)/PATP、Au(粗糙表面)/PATP/PANI膜的结构和成分,并以[Fe(CN)6]3-/[Fe(CN)6]4-为探针研究了其电子传递性能.结果表明用电化学组装法制备的PATP/PANI膜在纳米尺度上是二维有序的,且具有良好的电子传递性能.

Abstract: The ordered two-dimensional nano-structured conducting polymer films of a p-aminothiolphenol/polyaniline(PATP/PANI) on Au is fabricated by electrochemical-assembly (ECA) which is a new method first reported by our group. The surface topography, property and structure of PATP/PANI polymer films were investigated using scanning tunneling microscopy(STM), surface enhanced Raman scattering (SERS) and cyclic voltammetry. The results indicate that such oligomer films comprise ordered nano-structured clusters. The surface of the films is close-packed, homogeneous, flat in two-dimension. The electron transfer performance of PATP/PANI films is rather high.

Key words: Electrochemical-assembly, p-Aminothiolphenol, Polyaniline, Nano-structured ordered polymer films
