Fig. 6. Mechanical robustness of the hybrid EC films on PE cling wrap and PDMS film. (A) Schematic illustration of the structure of the PE cling wrap-based hybrid EC film. (B) The color-changing e-skin (EC film) on one finger (top), and PE cling wrap (bottom). (C) Upon folding and strong kneading, the PE-based hybrid EC film still displays the ability of coloring and bleaching, indicating excellent mechanical flexibility. (D) With 50% tensile strain stretching, the hybrid EC film on a PDMS substrate could also sustain its mechanical stability and electrochromic properties.
