An integrated visual energy system consisting of conjugated polymer electrodes is promising for combining electrochromism with storage. In this work, we obtained copolymer bifunctional poly(3,6-dimethoxythieno[3,2-b]thiophene-co-2,3-dihydrothieno[3,4-b][1,4]dioxin-3-ylmethanol)(P(TT-OMe-co-EDTM)) by one-step electrochemical copolymerization, which exhibits favorable electrochromic and capacitive storage properties. Because the synergistic effect PTT-OMe PEDTM, prepared copolymers show better flexibility. Moreover, morphology properties could be adjusted depositing different molar ratios 3,6-dimethoxythieno[3,2-b]thiophene (TT-OMe) 2,3-dihydrothieno[3,4-b][1,4] dioxin-3-ylmethanol (EDTM). The P(TT-OMe-co-EDTM) realized a high specific capacitance (190 F/g at 5 mV/s) recognizable color conversion. This work provides novel simple way to synergistically improve develop thiophene-based conducting polymers devices.

Abstract Exploring new materials and synthesis recipes are required to enhance the electrochromic performance especially, when used in solid-state devices. Here, polycrystalline gadolinium titanate (Gd 2 TiO 5 or GTO), synthesized using a simple reaction method, has been for this purpose by combining it with polythiophene (P3HT). The electrochemical investigation of Gd doped P3HT electrode carried out cyclic voltammetry (CV) impedance spectroscopy (EIS), which reveals dominance diffusion-controlled mechanism over charge storage on surface as compared electrode. device shows color modulation at 515 nm 670 wavelengths contrast high 79% 42%, respectively, under an external bias low ±1.4 V. prepared switches between maroon transparent state less than second (±1.4 V) coloration efficiency 346 cm /C. improved cycle life 100 switching cycles both wavelengths, makes more suitable real-life applications.
