摘要：

Thiophene adsorbed on a roughened gold electrode was studied in an aqueous solution at various potentials from 0 to 1.0 V vs. SCE by use of surface enhanced Raman scattering. It was found that thiophene oligomers and polythiophene were produced on the electrode surface at potential ranges of 0-0.6 V and 0.8-1.0 V, respectively. This potential range is significantly low compared to the potential used in the conventional electropolymerization of thiophene monomer (1.6 V vs. Ag/AgCl) in acetonitrile medium).
