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。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.
