“…Carbazole is a cheap monomer, which has good charge carrier properties so addition with other carbon based materials can be used in many applications such as solar cells [12,13], (bio)sensors [14][15][16] and supercapacitors [17][18][19][20]. Conducting polymers, such as polyaniline [21], polythiophene [22], polycarbazole [23] and poly(N-vinylcarbazole) [24], polymethylcarbazole [25], and nanomaterials, such as RuO 2 [26], MnO 2 [27], nanoclay [28] and TiO 2 [29], are pseudo-capacitive materials that have relatively high specific capacitance. However, limited poor stability was obtained for these materials owing to the redox reaction results in degradation problems [30][31][32].…”

In this study, graphene oxide (GO) is chemically reacted with sodium borohydride (NaBH 4 ) to form reduced graphene oxide (rGO). rGO, polycarbazole (PCz)/rGO and PCz/nanoclay/rGO materials were obtained by chemical polymerisation method. These three materials were characterised by Fourier-transform infra-red spectroscopy-attenuated transmission reflectance, scanning electron microscopy, energy-dispersive X-ray analysis, cyclic voltammetry (CV), galvanostatic charge-discharge and electrochemical impedance spectroscopy. The PCz/nanoclay/rGO nanocomposite shows significantly improved capacitance (C sp = 187.78 F g −1 ) compared to that of PCz/rGO (C sp = 74.18 F g −1 ) and rGO (C sp = 20.78 F g −1 ) at the scan rate of 10 mV s −1 by CV method. The supercapacitor device performance results show high power density (P = 1057.81 W kg −1 ) and energy density (E = 1.7 Wh kg −1 ) obtained from Ragone plot for PCz/nanoclay/rGO material. Stability tests were also examined by the CV method for 1000 cycles.
