Fig. 4. Electrochemical performance of the EC hybrid film. Cyclic voltammograms of the hybrid EC film (A) at different potential scan rates from 30 to 100 mV s⁻¹ and (B) at a scanning rate of 80 mV s⁻¹ in the potential range of −0.8 (colored) to 0.2 V (bleached). (C) Cyclic performance of the hybrid EC film. (D) Transmittance spectra of 30 nm (solid line) and 150 nm (dashed line) at bleached state (0.4 V) and colored state (−1.0 V).
