Abstract

See full text

A flexible variable emissivity electrochromic device and a preparation method thereof are disclosed. The device includes a working electrode, a gel electrolyte layer, and a counter electrode sequentially from top to bottom. The working electrode includes a flexible polymer film and a metal film, the flexible polymer film is a surface-modified film and/or a film with a transition layer plated on a lower side thereof, and the metal film is deposited on the surface-modified film or the transition layer. The electrolyte layer includes a porous membrane and an electrolyte. The electrolyte is infiltrated in the porous membrane. The electrolyte includes an electrochromic material containing metal ions and a solvent, the metal ions enable reversible electrodeposition and dissolution, and metal of the metal ions is different from that used in the metal film. The preparation method includes preparing and assembling a working electrode, a gel electrolyte layer and a counter electrode.
