Abstract
Self-assembled micro/nanotubes of polyaniline(PANI) with a high conductivity(10~(-2)～10~(-1)S/cm) were synthesized by a template-free method in the presence of hydrofluoric acid(HF) as the dopant.The formation probability of PANI-HF micro/nanotubes was nearly 100% when the molar ratio of / was equal to 0.5.The SEM and TEM images revealed that the average diameter of the micro/nanotubes was about 85～420 nm.Besides,it was found that the diameter and conductivity of micro/nanotubes at room-temperature increase with the increase of / ratios.The micro/nanotubes characterized by FTIR and UV-Visible absorption spectrums are identical to the emeraldine salt state of PANI.
