(a) An SEM image of the released PPy@CNT paper electrode after pre-stretching. Scale bar, 50 μm. (b) An SEM image of the stretched PPy@CNT paper electrode. Scale bar, 50 μm. (c) GCD curves from 0 to 600% strain at a charging/discharging current of 2.5 mA. (d) Capacitance enhancement ratio obtained from GCD curves as a function of the tensile strain. (Insets are photos of the supercapacitor at a fully released state and 600% strain.)
