中文摘要：

通过高能球磨方法引发樟脑磺酸（CSA）对本征态聚苯胺（PANI）的固相掺杂反应，制备了樟脑磺酸掺杂聚苯胺（PANI-CSA）粉末,采用SEM，XRD，FT-IR等分析方法对所得的PANI-CSA进行了形貌和结构表征，采用四点探针法对电导率进行了测定,FT-IR图谱的变化反映了聚苯胺的质子化过程，而XRD谱图表明，聚苯胺分子链在外力诱导下形成了有利于电荷传导的取向排列,系统地研究了球磨时间对掺杂率和电导率的影响规律，结果表明，固相掺杂具有较高的掺杂速率，其电导率和掺杂率均随球磨时间先增大后减小，其最高电导率可达到3．25S／cm，对应掺杂率为0.31。

英文摘要：

Polyaniline （PANI） base was doped with camphorsulfonic acid （CSA） in the solid state by high-energy ball milling. The morphology and structure of the as-made PANI-CSA salt were characterized by SEM, XRD and FT-IR spectroscopy, and the conductivity of the PANI-CSA was measured by a four-probe method. The protonation of polyaniline base is reflected by the changes in the infrared spectra. Evidenced by the XRD spectra, alignment of the polyaniline chain was induced by the ball milling, which is beneficial for electric charge transfer. The effect of the milling time on the conductivity and the doping level was also investigated. The results showed that the solid-state doping occurred with a fast rate, and both the conductivity and the doping level increased in the early stage of ball milling, and then dropped down. A maximum of conductivity of 3.25 S/cm was reached, corresoonding to a doping level of 0.31.
