中文摘要：

以樟脑磺酸（CSA）为掺杂剂、过硫酸铵为氧化剂，在水溶液体系中通过苯胺原位聚合制得直径为300～600nm的聚苯胺纳米矩形管，其导电率为0．1～1S／cm。通过扫描电镜（SEM）和透射电镜（TEM）对产物的形貌进行表征，发现n（CSA）／n（ANi）将影响产物的形貌。利用傅立叶红外光谱（FT-IR）和紫外-可见光谱（UV-vis）对聚苯胺分子结构进行表征，发现产物是质子化掺杂的聚苯胺。通过X射线衍射（XRD）分析发现，聚苯胺纳米矩形管比纤维结构具有更好的分子链排列规整性。

英文摘要：

Polyaniline（PANI） nanotubes with rectangular cross section, which have 300-600nm in outer diameter and the conductivity of 0. 1- 1S/cm, are synthesized via a in-situ polymerization with （1S）-（ q-）-10-camphorsu- lfonic（D-CSA） as dopants. PANI nanotubes are characterized by SEM and TEM. The results show that the ratios of n（CSA）/n（ANi） greatly affect the morphology of PANI nanotubes. The structure of PANI nanotubes are characterized by FT-IR and UV-vis spectrum. The result indicates that prepared PANI nanotubes are in doped state. The X-ray diffraction（XRD） tests show that the molecules of PANI with rectangular nanotubes have high orientations and orderly arrangements.
