Enhancing the Supercapacitive and Conductivity Properties of Polypyrrole via In-situ Polymerization with HY Zeolite Nanoparticles

摘要: Highly stable zeolite HY/polypyrrole composite material was successfully fabricated by applying in-situ chemical polymerization approach. The functional properties of the prepared HY particles/polypyrrole were systematically inspected using XRD and FT-IR characterization techniques. Thermal stability optical consistently studied TGA UV–Vis spectroscopy value band gap energy (Eg) produced nanocomposite lower than values its individual components. Cyclic voltammetry studies concluded that electrode with mass ratio ~ 0.4 at cold conditions ~ 0 °C exhibited highest specific capacitance ~ 310 F g−1 ionic conductivity ~ 1.7 S cm−1. 0 °C revealed a capacitance retention ~ 93.4%, while other 25 °C possessed retention ~ 72.4% after 500 charge/discharge cycles. electrochemical impedance (EIS) measurement for optimized materials confirmed cyclic long term cycling about 5000 cycles as result higher conductivity between active species before cycling.
