Özet

Poly (EGDMA-co-VPCA)/SWCNT composite film is successfully synthesized on Ni foam substrate by surface polymerization technique. Energy storage properties of Ni foam/poly (EGDMA-co-VPCA)/ SWCNT composite electrode are investigated via cyclic voltammetry, galvanostatic charge-discharge and electrochemical impedance spectroscopy. The as-prepared Ni foam/poly (EGDMA-co-VPCA)/ SWCNT composite electrode exhibits high specific capacitance of 100 F/g at 5 A/g, high power density of 3285.0 W/kg at 8.5 Wh/kg energy density, capacitive retention of 77.7% after 5000 charge-discharge cycles and excellent chemical stability.
