Abstract
Integrating electrochromism into a supercapacitor can provide a multifunctional electrochromic supercapacitors (ESC) for smart windows, portable and wearable electronics. Polyaniline (PANI) as the most promising electrode material for ESC, is limited by the poor solution processability and inferior cyclic stability. The strategy we propose here is to add 1,3,6,8-pyrenetetrasulfonic acid (1,3,6,8-Psas) as an anchored dopant during the polymerization of PANI. Its large steric hindrance can play a role in inter-chain support and reduce the effect of inter-chain interaction for obtaining the excellent solution process ability. In addition, 1,3,6,8-Psas can also act as a crosslinking agent, which can adjust the morphology of PANI to provide the composite electrode with a rich pore structure for increased contact area with electrolyte and thereby improved ion transmission. The area specific capacitance of the original PANI-WO3/FTO composite electrode calculated from the CV curve at 100 mV/s is 38.71 mF/cm2, while the 1,3,6,8-Psas doped PANI-WO3/FTO composite electrode is 72.11 mF/cm2, which indicates that the introduction of 1,3,6,8-Psas could greatly improve the electrochemical property of the solution processed PANI. The capacitance retention rate of the composite electrode with 1,3,6,8-Psas as anchor doping agent is 70.12% after 1000 cycles, while the capacitance retention rate of the PANI-WO3/FTO electrode with 1000 cycles is only 43.34%, which indicated that the anchoring effect of 1,3,6,8-Psas can support the linking of PANI and prevent the impact failure of the PANI chain skeleton.Funding Information
