以樟脑磺酸(HCSA)为掺杂剂,FeCl3为氧化剂,通过化学氧化聚合合成了聚(3,4-乙撑二氧噻吩)/樟脑磺酸(PEDOT/HCSA)复合材料;采用FTIR和SEM对其结构和形貌进行了表征;探讨了掺杂剂与单体摩尔比、氧化剂用量和反应时间对产品导电性能的影响;分析了产品的电化学性能。结果表明,当n〔3,4-乙撑二氧噻吩(EDOT)〕:n(樟脑磺酸):n(氯化铁)=2:1:40,反应时间41 h时,复合材料具有良好的导电性能和电化学性能,电导率为10.4 S/cm,经150次充放电老化后比容量可保持在140 F/g左右,是一种潜在的超级电容器电极材料。
Poly (3,4-ethylenedioxythiophene) / camphorsulfonic acid (PEDOT / HCSA) composites were synthesized by chemical oxidative polymerization using camphor sulfonic acid (HCSA) as dopant and FeCl3 as oxidant. FTIR and SEM The structure and morphology of the product were characterized. The effects of molar ratio of dopant to monomer, amount of oxidant and reaction time on the electrical conductivity of the product were discussed. The electrochemical properties of the product were analyzed. The results show that the composites have good properties when n (3,4-ethylenedioxythiophene) (n-camphorsulfonic acid): n (ferric chloride) = 2: 1:40 and the reaction time is 41 h Conductivity and electrochemical performance, the conductivity of 10.4 S / cm, after 150 charge and discharge aging capacity can be maintained at about 140 F / g, is a potential supercapacitor electrode material.
