摘要：We electrochemically deposited one layer of the electrochromic (EC) polymer poly(3,4( 2,2-dimethylpropylenedioxy)thiophene) on ITO-coated PET substrate. Scanning electron microscopy showed that the polymer film was nanostructured, which becomes desirable for improving ion diffusion and color changing. We built an equivalent circuit model to simulate the EC kinetics using the measured alternating current impedance data. Furthermore, we assembled a set of smart goggles with good flexibility; these exhibited the ability to change colors quickly at a low driving voltage and demonstrated their stability through tens of thousands of test cycles.
