Effect of Different Protonic Acid on the Rate of the Electrochemical Polymerization of Anil ine
摘要/Abstract
利用循环伏安方法在不同质子酸掺杂下电化学聚合苯胺,并以聚合电量随循环次数的变化测定苯胺电聚合的速率.结果表明苯胺的聚合速率受[H+]的强烈影响:当[H+]低于7.5 mol/L时,苯胺的聚合速率与[H+]之间是一级反应,苯胺溶液中[H+]的存在加速了苯胺的聚合;当[H+]高于7.5mol/L时,苯胺的聚合速率与[H+]之间是零级反应.建立了质子酸对苯胺电化学聚合的有关速率方程,该速率方程与实验结果相符.
The elect rochemical polymerization of aniline were carried out by using the cyclic voltmmetric method in the different protonic acid.The rates measurements of the elect rochemical polymerization of aniline demonst rated by the polymer elect ric quantity depend on cyclic number. The polymerization rate of aniline is strongly affected by [H+]concent ration.The polymerization of aniline is first order with respect to the concen tration of [H+]below 7.5 mol/L.The presence of [H+]in the aniline solution plays an important role in in creasing the polymerization rate.The polymerization of aniline is zero order with respect to the concent ration of[H+]exceed 7. 5 mol/L.Based on the experimental data,a rate equation dealing with the concent ration of ani2 line and [H+]is presented at a given acid concent ration.The dependence of the polymerization rate of aniline on the concent ration of aniline and [H+]in the rate equation is in good agreement with the experimental data.
