摘　　要：以氯金酸(HAuCl4)为氧化剂,在两种不同无机酸(HCl和H2SO4)的掺杂下,通过调节反应体系中混合溶剂的醇水比例,用一步氧化苯胺聚合法成功制备了不同形貌的纳米聚苯胺及聚苯胺/金复合材料.通过扫描电子显微镜(SEM)、紫外可见吸收光谱(UV-Vis)和红外光谱(FT-IR)对产物的形貌和结构进行了表征.在此基础上,进一步讨论了聚苯胺/金复合材料可能的形成机理.With chloroaurate acid （HAuC14） acted as the oxidant, different morphological poly- aniline and polyaniline/Au nanocomposite materials doped with two different kinds of inorganic acid （HC1 and H~ SO4） were successfully fabricated by one-step oxidation polymerization of aniline via adjusting the volume percent of ethanol/water of mixed solvent. The morphological evolution of the so-obtained products was observed via scanning electron microscopy （SEM）. The chemical and electronic structures of the as-prepared materials were studied using Fourier transform infrared （FT-IR） and UV-Vis spectroscopies. Based on the characterizations, the possible formation mechanism of polyaniline/Au nanocomposite was also discussed.
