摘要：
An electroactive polymer poly[4,7-bis(3,6-dihexyloxy- thieno[3,2-b] thiophen-2-yl)]benzo[c][1,2,5] thiadiazole is synthesized and applied as a color-changing electrode material in supercapacitors via spray coating method. Using poly(3,4ethylenedioxythiophene) as the negative electrode, the all-polymer asymmetric supercapacitors provide an energy density of 3.5-6.3 W h kg(-1) and power density of 0.6-8.8 kW kg(-1).
