Growing ordered arrays of vertically aligned copolymer nanowires for supercapacitors with high stability

In this report, we present a novel platform to study the formation of delicate ordered vertically aligned copolymer nanowires array with EDOT and Py as the initial source. The resultant samples exhibit a specific capacitance of 187 F g⁻¹ with the current of 0.1 A g⁻¹ in 0.1 M LiClO₄ aqueous electrolyte. When the current was set as 8 A g⁻¹, the energy density was 16.9 W h kg⁻¹ and the power density was 5480 W kg⁻¹ with good cycling stability (remained stable after 5000 cycles). The multicomponent copolymer nanowire array has great potential to become a versatile and efficient material for next generation of endurable electrochemical supercapacitors.
