| Abstract: | 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. |
