摘要
采用界面聚合法合成高氯酸掺杂聚苯胺纳米纤维,设计正交实验考察高氯酸的浓度、过硫酸铵/苯胺的摩尔比、反应时间对聚苯胺的比容量、电容器的充放电效率的影响。结果表明,对于聚苯胺的比容量而言,影响最大的是过硫酸铵/苯胺的摩尔比,其次是反应时间,高氯酸浓度的影响最小。对聚苯胺电容器充放电效率而言,影响最大的是高氯酸的浓度,其次是过硫酸铵/苯胺的摩尔比,反应时间的影响最小。综合各项指标,确定最佳工艺条件为过硫酸铵/苯胺摩尔比为1.5,高氯酸浓度为0.5mol/L,反应时间为7 d。
Use interfacial polymerization to synthesize perchloric acid doped polyaniline nanofibers,design orthogonal experiments to study the impact of the reaction conditions on the electrochemical properties of polyaniline.For the specific capacity of polyaniline,The greatest impact is the ammonium persulfate / aniline molar ratio,followed by the influence of the reaction time,the concentration of perchlorate minimum.For the polyaniline capacitor charge-discharge efficiency,the greatest impact is the concentration of perchlorate,followed by ammonium persulfate / aniline molar ratio,the reaction time with minimal impact.Therefore,optimum conditions are ammonium persulfate / aniline molar ratio of 1.5,perchloric acid concentration of 0.5 mol / L,the reaction time is 7 hours.
