超级电容器已经成为需要快速充放电循环和高功率密度的系统的有吸引力的能量存储装置。由于聚合物倾向于形成高度多孔的膜并表现出可逆的氧化还原活性，因此在此应用中进行聚合物研究的进展已经显示出巨大的前景。在这篇文章中，我们提出了一种新的三芳胺-噻吩混合导电聚合物用于电荷存储，聚（三（4-（噻吩2-基）苯基）胺）（pTTPA），它可以电化学沉积成高度多孔的薄膜或模板纳米管结构。pTTPA代表并入超级电容器电极中的第一树枝状聚合物材料，其在乙腈中的100 mM四氟硼酸四丁基铵中产生950 +/-49 F/g的显著高峰电容。我们的多功能平台设计为电能存储聚合物的新合成机会打开了大门。
Supercapacitors have emerged as attractive energy storage devices for systems requiring rapid charge-discharge cycles and high power densities. Progress in conducting polymer research for this application has shown tremendous promise due to the polymers' tendency to form highly porous films and exhibit reversible redox activity. In this Communication, we present a new triarylamine-thiophene hybrid conducting polymer for charge storage, poly(tris(4-(thio-phen2-yl)phenyl)amine) (pTTPA), which can be electrochemically deposited into highly porous films or templated nanotubular structures. pTTPA represents the first dendritic polymeric material incorporated in supercapacitor electrodes yielding a remarkably high peak capacitance of 950 +/- 49 F/g in 100 mM tetrabutylammonium tetrafluoroborate in acetonitrile. Our versatile platform design opens the door to new synthetic opportunities for electrical energy storage polymers.
