Abstract

Carbon foam (CFDT) has been fabricated by polycondensation of resorcinol and formaldehyde, using two kinds of polymethylmethacrylate as pore generators. In order to increase the specific surface area and improve the surface activity and wettability of the material in the electrolyte, physical activation (A-CFDT) with CO₂ and chemical modification (N-CFDT) with HNO₃ were carried out. CFDT showed poor supercapacitor properties, with a specific capacitance of 80.1 F/g at a 10 mV/s scan rate. N-CFDT exhibited the largest specific capacitance, with a value of 137.8 F/g at a 10 mV/s scan rate, when using 6 M KOH as the electrolyte. N-CFDT exhibited excellent cycle life stability as well.
