Problems solved by technology

Electrochromic cloth devices prepared with traditional structures usually use bulky metal fabrics as cloth and electrode materials, which are stacked together. This kind of metal conductive fabric stacked device structure is prone to short circuits, and it is not easy to carry out subsequent processing and large-area preparation. ; and the metal fabric is not corrosion-resistant, and the obtained device is relatively thick and heavy, and does not have processing and practicability

Embodiment example 1

[0022] figure 1 is the plane structure diagram of the electrochromic cloth device, figure 2 is the side structure diagram of the electrochromic cloth device. Spray the ITO conductive paste on the synthetic fiber cloth 1 according to the template, and bake at 100°C for 5 minutes to obtain a wide ITO film 2 and a narrow ITO film 3 in parallel intervals, as the electrodes of the electrochromic device, and each wide ITO film The width of the electrodes is 3-5 millimeters, the width of each narrow ITO film electrode is 1-2 millimeters, and the interval between the ITO films is less than 1 millimeter. Then, the electrochromic material 4 is sprayed on the wide ITO film 2 and baked at 80° C. for 5 minutes. Finally, the electrolyte 5 is sprayed on the cloth covering the ITO film electrodes 2, 3 and the electrochromic material 4, and covered with a thin transparent polyethylene film 6, and cured under a 365 nm ultraviolet lamp for 5 minutes to obtain an electrochromic cloth device. ...

Abstract

The invention relates to a manufacturing method of electrochromic cloth. According to the method, an all-solution preparing and processing process is adopted, and electrodes are membranes formed by ITO electro-conduction slurry after being dried, in a planar cross distribution structure. The manufacturing method is simple, the cost is low, the prepared electrochromic cloth is thin, light, resistant to flexion and high in practicability, subsequent processing is facilitated, and large scale production is easy to achieve.

Description

technical field [0001] The invention relates to a method for making electrochromic cloth. Background technique [0002] Electrochromic technology is based on the electrochemical redox reaction of electroactive substances under the action of an applied electric field or current, which causes reversible changes in the transmittance, reflectivity and absorptivity of light of different wavelengths, so that in The appearance shows the phenomenon of different color changes. Electrochromic technology has been applied in fields such as life and military affairs, such as intelligent color-changing windows, electronic displays, car rearview mirrors, etc. In the military field, it can be mainly used for the preparation of intelligent camouflage cloth. Traditional electrochromic devices mainly adopt a sandwich-type vertical layered structure, which can be divided into a transparent conductive layer, an electrochromic layer, an electrolyte layer, an ion storage layer, and a transparent...
