Tungsten oxide electrochromic thin film is an indispensable electrochromic layer material for assembling a large area building glass. In general, it requires architectural glass to have a long service life. So, how to improve the service life of electrochromic devices such as architectural glass?

In this regard, experts said that surface modification of the tungsten oxide electrochromic film on the FTO conductive glass surface can be carried out to improve the service life of electrochromic devices. Also, by activating the contact angle, the PVDF-HFP/DMF quasi-solid electrolyte and the electrochromic layer can be closely adhered to reduce cracking during the cycle. In addition, in order to increase the coloring efficiency and the color change response speed, it is possible to etch the silver slurry and brush the silver nanowire inside the large-area glass so that various parts of the device can be simultaneously discolored when an external voltage is applied.
