Özet
This study demonstrates the exceptional supercapacitive performance of a novel P(EGDMA-TAVS)–graphene composite on nickel foam (NF) substrate. The three-dimensional porous architecture, combining the high conductivity of graphene with the robust polymeric framework of poly(ethylene glycol dimethacrylate-trimethylolpropane allyl ether vinyl sulfonate) [P(EGDMA-TAVS)], enables outstanding electrochemical properties. The p(EGDMA-TAVS)–graphene/NF electrode demonstrates specific capacitances of 963.9, 817.2, 746.1, 716.4, 650.6, and 603.5 F g−1 when tested at scan rates of 10, 20, 30, 50, and 70 mV s−1, respectively. The enhanced interfacial adhesion provided by p(EGDMA-TAVS), together with graphene’s efficient electron-transport network on the nickel foam current collector, yields an energy density of 40.3 Wh kg−1 at a power density of 4773.6 W kg−1 in 3 M KOH. The p(EGDMA-TAVS)–graphene/NF electrode preserves 95.6% of its starting capacitance over 2500 cycles at 6 A g−1. These results position the P(EGDMA-TAVS)-graphene/NF electrode as a promising candidate for high-performance energy storage applications.
