| 聚毗咯(PPy)除具有其它芳杂环导电聚合物所共有的特征外，还兼有导电率高、易于制备及掺杂、稳定性好、电化学可逆性强等特点。这些优点都是其它众多导电高聚物无法比拟的。1979年，Diaz和Kanazawa等人初次报道了以电化学方法合成优质导电聚吡咯膜，并对其电化学性质进行了研究。自此以后，人们便争相研究这一具有“导电聚合物中最具吸引力和前途”美誉的新材料。以APS为氧化剂，以甘氨酸铜为模板合成棒状聚吡咯导电聚合物微/纳米结构材料。其结构和形态通过红外光谱、X-射线粉末衍射、扫描电镜、测试手段进行了表征，利用SDY-4型四探针电阻测试仪测定其电导率。研究导电聚合物微管壁厚与导电率的关系 |

| PVP poly (PPy) ,in addition to other conductive polymers Heteroaromatic, shared characteristics, but also a combination of high conductivity, ease of preparation and doping, good stability and electrochemical characteristics of reversible and strong. These advantages are many other conductive polymers can not be compared. In 1979, Diaz and Kanazawa, who first reported the electrochemical method for synthesis of high-quality conductive polypyrrole film and its electrochemical properties were studied. Since then, people will be eager to study this with "conducting polymer in the most attractive and the future of" the good reputation of the new materials. APS as oxidant is to glycine copper rod for the template synthesis of conducting polymer polypyrrole micro / nano-structured materials. Its structure and form through infrared spectroscopy, X-ray powder diffraction, scanning electron microscopy, were characterized by means of testing the use of type SDY-4 four-probe resistance measured conductivity tester. Conductive polymers and conductive micro-tube wall thickness of the relationship between the rate will be studied. |
