中文摘要：

采用单体聚合-溶液浸润-聚合物成管同时进行的方法，在氧化铝多孔模板（AAO）中制备了聚乙撑二氧噻吩（PEDOT）纳米管。通过形貌分析推断PEDOT纳米管在孔道中的生长包括两个过程：首先是聚合物溶液浸润整个孔道；然后是聚合过程中生成的阳离子自由基和掺杂态的PEDOT由于带正电荷而在孔道壁产生“钉扎”效应。XRD分析显示，在孔道内生成的PEDOT分子链具有一定的取向性。进一步研究表明，聚合物的吸附及单体聚合后的吸附，在模板壁导致不同的分子链排列，使PEDOT纳米管分子排列有序性受到影响。采用四探针和扫描隧道显微镜（STM）方法研究了纳米管光电性能。

英文摘要：

Polymer ethylenedioxy thiophene （PEDOT） nanotube was fabricated by a template synthesis method. Accordance to the size of porous porous anodic aluminum oxide （AAO） template, it was presumed that two processes happen successively during the formation of nanotube. The first step was the soaking of polymerizing solution into porous template, and the second step was the adsorption of free charged cationic group and to dope PEDOT onto the negative charged template surface. A XRD investigation showed well orientation of PEDOT chain in tube was formed during the synthesis process and it was also found that different arranging of molecular chain reduce the ordered structure of PEDOT nanotube. The single nanotube exhibited a conductivity about 5.5 - 17.6 S/cm, which was higher than that of a nanotube pellet due to the high contact resistance between adjacent nanotube.
