摘要

以氢氟酸为掺杂剂

采用无模板法制得了高电导率（10-2～10-1S/cm）聚苯胺微/纳米管（d=85～420 nm）.当［HF］/［An］=0.5时所得微/纳米管的形成机率高达100%.发现微/纳米管的直径和电导率均随［HF］/［An］比例的增加而增加.FTIR

UV-Vis

XRD结构表征证明所得的聚苯胺微/纳米管为掺杂态.

Abstract

Self-assembled micro/nanotubes of polyaniline (PANI) with a high conductivity (10-2～10-1S/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 ［HF］/［An］ 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 ［HF］/［An］ ratios.The micro/nanotubes characterized by FTIR and UV-Visible absorption spectrums are identical to the emeraldine salt state of PANI.
