Novel Stretchable Ambipolar Electrochromic Devices Based on Highly Transparent AgNW/PDMS Hybrid Electrodes

Abstract Novel stretchable ambipolar electrochromic devices (ECDs) based on highly transparent silver nanowire (AgNW)/polydimethylsiloxane (PDMS) hybrid electrodes are successfully prepared in this study. A facile fabrication methodology has been proposed for the preparation of highly transparent and stretchable ECDs by judiciously combining electrochromic materials and AgNW/PDMS hybrid electrodes. Additionally, these stretchable ECDs are composed of an ambipolar system based on triphenylamine derivatives and heptyl viologen. The obtained stretchable ECDs based on the AgNW/PDMS hybrid electrodes are initially colorless; these ECDs exhibit high transparency at the neutral state and reveal various colors according to different ambipolar redox couples at the related applied potentials.
