摘要

Electrochromic polymer films were patterned by a soft lithography technique using a nanopatterned PDMS mold to generate submicron size gratings. The redox currents (i_p) were significantly increased due to the facilitated diffusion of counter ions associated with redox processes at the EC polymer electrode as analyzing cyclic voltammetry (CV) performed at different scan rates (v). As a result of such facilitated charge transport, the electrochromic (EC) properties of the patterned electrode were greatly enhanced to give high EC efficiency, including the coloration (E_c) and bleaching efficiencies (E_b).
