中文摘要:

采用化学氧化法合成一种粉末状超级电容器电极用导电高分子材料聚吡咯,通过引入掺杂剂TSA,使合成的PPy的电导率得到有效的提高,电化学电容性能得到改善;研究掺杂剂浓度、单体浓度、氧化剂浓度、聚合时间及反应温度对Py转化率和PPy电导率、比电容等性能的影响.结果表明,TSA用量对Py转化率和PPy的电导率的影响不大,但对PPy比电容的贡献比较明显PPy的产量随Py用量增加逐步增加,转化率却呈下降趋势,PPy的电导率和比电容随Py用量增加先增加而后下降;Py的转化率随FeCl3浓度增加而规则地升高,PPy的电导率和比电容先基本保持不变,之后反而降低;随着tp的增加,Py的转化率、电导率和比电容有显著的增加;在低温下有利于提高PPy的电导率.

英文摘要:

A powdery conductive macromolecular material-polypyrrole with its conversion rate of Py was synthesized with chemico-oxidative method, the conductivity of synthesized PPy was effectively improved by introducing inclusion mixture TSA, and its performance of electrochemical capacity was also improved. The influence of the concentration of inclusion mixture, monomer concentration, oxidizer concentration, polymerization time, and reaction temperature on the conversion rate of Py and conductivity and specific capacity of PPy was investigated. The results showed that the influence of TSA dosage was insignificant while, instead, made a remarkable contribution to the specific capacity of PPy. The yield of PPy increased gradually with the dosage of Py, but its conversion rate exhibited decreasing tendency. The conductivity and specific capacity of PPy increased at first with the dosage of Py and then decreased. The convesion rate of Py was remarkably and regularly increased with the concentration of FeCl3 while the conductivity and specific capacity of PPy kept basically constant at first and then decreased, instead. The conversion rate, conductivity, and specific capacity of Py was remarkably increased with tp. Low temperature was of benefit to improving the conductivity of PPy.
