The electrochromic modulation of plasmonic metasurfaces showing structural colors is a promising strategy to realize dynamic electronic reflective displays. However, hybridizing electrochromic polymers with large-area plasmonic metasurfaces remains challenging. In this study, we present a poly(3,4-ethylenedioxythiophene) (PEDOT)-coated gold nanodisk (PCGN) metasurface, which is fabricated based on techniques of large-area anodic aluminum oxide template-assisted deposition and electrochemical polymerization. Experimental and numerical results demonstrated that fast and reversible electrochromic modulation was realized within the PCGN metasurface. The wavelength control of the localized surface plasmon resonance of the PCGN metasurface originated from the electrically driven refractive index change of the PEDOT layer. The PCGN metasurface is promising for the high yield manufacturing of devices applied in dynamic reflective displays.
