Water Plasma Functionalized CNTs/MnO₂ Composites for Supercapacitors

Figure 5

(a) Cyclic voltammograms obtained at a scan rate of 10 mVs⁻¹ for untreated MWCNTs/MnO₂ and wpCNTs/MnO₂ under different plasma conditions ((A): untreated, (B): 75 W, 135 Pa, (C): 140 W, 135 Pa, (D): 10 W, 135 Pa). (b) Cyclic voltammograms of nanocomposite wpCNTs/MnO₂ (10 W, 135 Pa) at different scan rates, 10, 20, 30, 40, 50, 100, and 150 mVs⁻¹.
