Abstract

We present the electrochemical polymerization and characterization of a stable and dopable polyindophenine derivative starting from monomer 5. The fabrication of supercapacitor devices was carried out by direct electrochemical polymerization on an ITO-coated slide. Furthermore, the galvanostatic and potentiostatic experiments conducted on these supercapacitors have shown that the polyindophenine-derivative material has very good cyclability, over a potential range of 1.4 V, and a maximum capacitance of 140 F g(-1).

摘要

我们展示了从单体5出发的一种稳定且可掺杂的聚吲哚酚衍生物的电化学聚合及其表征。超级电容器器件是通过在涂有ITO的载玻片上直接进行电化学聚合制备的。此外，对这些超级电容器进行的恒电流和恒电位实验表明，聚吲哚酚衍生物材料在1.4 V的电位范围内具有非常好的循环稳定性，最大电容为140 F g⁻¹。
