Figure 5. Electrochemical properties of the GPPy nanohybrids measured in 1 M sulfuric acid.

CV curves of (a) GPPy60 and (b) GPPy100 samples with different PPy/graphite weight ratios at a 25 mV s⁻¹ scan rate; (c) CV curves of 8GPPy60 versus 8GPPy100 recorded at a 50 mV s⁻¹ scan rate; and CV curves of (d) 8GPPy60 and (e) 8GPPy100 recorded at scan rates ranging from 1–50 mV s⁻¹.
