Abstract

Abstract : 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, 4‐ethylenedioxythiophene) 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 .
