| description | Electrochromic materials have good development prospect under the development concept of promoting low carbon and energy saving. In order to explore the efficient, simple and excellent preparation process, the polymer electrochromic film was prepared by the electrostatic spray method combined with the in-situ elution method. According to the color adaptability and solubility of the electrolyte salt, tetrabutylammonium perchlorate (TBAP) was selected as the template, and different proportions of electrolyte salt were added to the easy-to-process TPA-OMe-PA solution, then film was deposited on the surface of the ITO glass by electrostatic spray technology. After that, the electrolyte salt was precipitated by in-situ washing method. The morphology of the film was analyzed using scanning electron microscope, and the electrochromic properties of the film were studied using the electrochemical workstation combined with ultraviolet/visible/infrared spectrometer. The research results show that the polymer film prepared by electrostatic spray technology and in-situ elution method have multi-level pore structure and excellent electrochromic properties. Especially when the electrolyte content is 33.3%(mass fraction), the multi-layer porosity is the highest, and the electrochromic performance is the best. The bleaching time/coloration time is reduced to 0.6 s/1 s, and the coloration efficiency reaches 608.2 cm2·C-1, which is the best record for the polyamide based electrochromic film. |
