Abstract

The invention provides a two-color adjustable electrochromic thin film device. The device comprises an electrochromic layer, an electrolyte layer and a conductive ion storage layer in certain colors;an electrolyte is applied onto the electrochromic layer to form the electrolyte layer, then the ion storage layer in the certain colors wraps the electrolyte layer, and curing resin is utilized for edge sealing curing to form the two-color adjustable electrochromic thin film device; the conductive ion storage layer in the certain colors is formed by uniformly mixing a nano conductive material, anion storage material and thermosetting resin and then adding dyes in the certain colors, and then wraps the electrolyte layer. According to the two-color adjustable electrochromic thin film device, organic electrochromic materials in different colors are selected, a new manufacturing process is utilized, the ion storage material and the nano conductive material in a traditional electrochromic device are uniformly mixed in the thermosetting resin, the oil dyes in different colors are added into the mixture, and conductive thin films with the ion storage function in different colors are prepared.

Description

technical field [0001] The invention relates to the field of photoelectric thin film materials, in particular to a two-color adjustable electrochromic thin film device. Background technique [0002] Electrochromic devices (Electrochromic Devices) means that by applying a certain voltage to the device, the color of the device will change, and when the voltage is removed, the device can remain in a colored or faded state (called memory effect). The core of this type of device is a color-changing material. With the change of the polarity and strength of the applied electric field, the color of the material and its reflection or transmission intensity of the incident light undergo reversible changes. [0003] A traditional electrochromic device consists of five parts: Transparent Conductive Electrode Layer, Electrochromic Material Layer, Electrolyte Layer, Ion Storage Layer and another layer transparent conductive electrode layer. In addition to the core electrochromic materia...
