•A novel carbazole-triphenylamine-based electrochromic film has been prepared.•The film could exhibit different colors as bluish green, light yellow and off-white.•The film can sensitively change its color within seconds.•The biggest different average emissivity dynamic of the film is 0.082.
4,4′-Di(N-carbazolyl)triphenylamine (DCBZ-TPA) is synthesized and its polymer film was deposited on ITO-glass through electrochemical polymerization. Electrochromic properties of the novel film were investigated by cyclic voltammetry and amperometric i–t curve. The optical properties of the film were investigated by UV–vis and FT-IR spectroscopy. The electrochromic film can sensitively change its color within seconds, which can be described as bluish green, light yellow and off-white. A biggest different average emissivity dynamic of the film is 0.082 in the wavelength of 8–14 μm.
