Water Plasma Functionalized CNTs/MnO2 Composites for Supercapacitors

Figure 3

Raman spectra of (A) wpCNTs/MnO2 (75 W, 135 Pa) before cycling, (B) wpCNTs/MnO2 (75 W, 135 Pa) after 2000 cycles (between 0-1 V), and (C) wpCNTs/MnO2 (75 W, 135 Pa) after 2000 cycles (between 0.1–0.8 V). Inset figure shows Raman spectra of (D) untreated CNTs and (E) wpCNTs (75 W, 135 Pa).
