Abstract

The invention provides a production method for a polyaniline electrochromatic composite film device, which belongs to the technical field of electrochromatic film production. The method includes: preparing polyaniline composite and polystyrene glue solution, adding the polyaniline composite into the polystyrene glue solution, well mixing, using ultrasonic for scattering to obtain polyaniline composite conductive liquid, and coating the conductive liquid on ITO (indium tin oxide) conductive glass or a conductive film to obtain a polyaniline electrochromatic composite film by means of painting or spraying; and bonding the polyaniline electrochromatic composite film with an electrolyte-contained conductive layer, drying at 50-60 DEG C for 2-3 hours, and using epoxy resin to seal the two layers all around to obtain the polyaniline electrochromatic composite film device. The polyaniline electrochromatic composite film device made by the method has the advantages of short response time, long recycling service life, high performance and the like, and the production method is simple and low in cost and has wide application prospect and high practical value.

Description

technical field [0001] The invention belongs to the technical field of electrochromic film preparation, and in particular relates to a preparation method of a polyaniline composite electrochromic film device. Background technique [0002] Electrochromism refers to the phenomenon that under the action of electric field and current, materials cause redox reactions through electrochemical processes to produce reversible discoloration. Electrochromic materials have great application value in many fields. According to different electrochromic Different properties and combinations of materials can combine different structures and special chromic devices. These devices can achieve continuous adjustment of yield and reflectivity in the visible spectrum, infrared spectrum and even microwave range, multi-color continuous change, and it also has a storage memory function, low voltage for color change, simple power supply, power saving, and is not affected by the environment. Small and...
