Colored electrolytes for electrochromic devices

Color tuning remains one of the main issues for electrochromic applications. Multicolored organic and inorganic materials have been largely studied. Herein, a novel approach color modulation is investigated: electrolyte coloration. The therefore not only due to but addressed thanks pigment addition in electrolyte, which allows endless possibilities. A symmetrical PEDOT:PSS based display WO3//V2O5 were elaborated order characterize this coloration process. PEGDMA/PEGMA copolymer gel was processed by thermal polymerization using AIBN colored four different pigments. Similar switching times capacities measured from another. This easy set up method multiplies achievable colors without altering device stability.
