Capacitance values of CNT/PPy composites. (A) Specific capacitance of PPy/MWCNT composites with different PPy thickness. The insets are CV curves of PPy/MWCNT composites with various PPy thickness (nm): 6, 15, 21, 28, 37, 51 and 100 nm in 1 M KCl solution at scanning rate of 100 mVs-1. (B) PPy thickness dependence of the charge transfer resistance of PPy/MWCNT composites. The insets are EIS curves of PPy/MWCNT composites with different PPy thickness.
