摘要: In this study, electrochemical responses of inkjet-printed multicolored electrochromic devices (ECD) were studied to evaluate the feasibility presenting multiple colors in one ECD. Metallo-supramolecular polymers (MEPE) solutions with two primary on flexible electrodes. By digitally controlling print dosages each species, printed EC thin film patterns can be adjusted directly without premixing or synthesizing new materials. The films then laminated a solid transparent electrolyte and conductive form an After applying dc voltage, ECDs exhibited great contrast transmittance change (ΔT) 40.1% high coloration efficiency 445 cm2 C–1 within short darkening time 2 s. also showed same s still had ΔT 30.1% under bending condition. This study demonstrated fabricate display d...
