Problems solved by technology

[0007] In order to solve the problems of the above-mentioned electrochromic reflective devices, the applicant thought of combining layers with different functions such as light reflection, conduction, and ion storage in the existing electrochromic reflective devices on the same substrate, thereby reducing the cost of the electrochromic reflective devices. The problem of high cost and reflection ghosting caused by the multi-layer structure, so the applicant made the substrate have light reflection, conductivity and ion storage functions at the same time through pre-processing, and replaced the existing battery-type electrochromic reflector with this substrate The multi-layer structure of ion storage layer / electrolyte layer / substrate / reflective conductive layer required by the device can reduce the cost of the process and improve the problem of reflection ghosting at the same time. Such a concept has not appeared in the existing patents and literature passed

Embodiment 1

[0065] The preparation method of the electrochromic reflective device of the present embodiment is as follows:

[0066] (1) Take a mirror-treated stainless steel plate, and Li + Ions are implanted into the stainless steel plate to form the light reflective conductive ion storage substrate.

[0067] (2) Take a glass as a transparent substrate, and coat a layer of indium tin oxide (ITO) on the transparent substrate to form the transparent conductive layer (the semi-finished product is expressed as "glass / ITO").

[0068] (3) Using a tungsten target at room temperature and a pressure of 40mtorr, using plasma sputtering coating technology, a layer of tungsten oxide is coated on the glass / ITO to form the electrochromic layer (the semi-finished product made Expressed as "glass / ITO / WO 3 ").

[0069] (4) Coat the frame glue around the light-reflective conductive ion storage substrate, but leave the inlet and exhaust port for electrolyte filling, and then apply the glass / ITO / WO 3 Pl...

Embodiment 2

[0072] Example 2 is to prepare an electrochromic reflective device in the same steps as Example 1, the difference is that the weight ratio of PC, EC and PAN is 1:0.5:0.3, and then an electrochromic reflective device containing a gel electrolyte is obtained. Chromogenic reflective device.

Embodiment 3

[0074] Example 3 is to dry the electrochromic reflective device prepared in Example 1 in a vacuum oven at a temperature of 60° C. to remove excess solvent, and make the electrolyte layer in it into a solid state, thereby obtaining an electrochromic reflective device containing a solid electrolyte. Chromogenic reflective device.

Abstract

The present invention relates to an electrochromic reflecting device, which comprises a transparent unit, a light reflection conductive ion storage substrate and an intermediate unit which is clamped between the transparent unit and the light reflection conductive ion storage substrate. The intermediate unit comprises an electrochromic layer and an electrolyte layer which are piled in sequence from the transparent unit towards the light reflection conductive ion storage substrate. The light reflection conductive ion storage substrate consists of a plurality of doped metal materials, which comprises a reflection zone adjacent to the transparent unit; wherein, the dope is selected from H <+>, Li <+>, Na <+>, K <+> or the combination of the substances; and thus the substrate has the functions of simultaneous reflection, conduction and ion storage.

Description

technical field [0001] The invention relates to an electrochromic reflective device, in particular to a battery-type electrochromic reflective device. Background technique [0002] Electrochromic reflective devices are one of the most popular reflective devices at present. At present, major automobile manufacturers have gradually begun to use electrochromic reflective devices as automobile anti-glare rearview mirrors. It can be seen that this kind of electrochromic reflective devices It has considerable potential in the use of auto parts. Currently known electrochromic reflective devices can generally be classified into solution-phase, hybrid and battery-like electrochromic reflective devices. [0003] The solution-phase electrochromic reflection device includes a transparent substrate, a transparent conductive layer, an electrochromic solution, a reflective conductive layer and a substrate. After applying a direct current of several volts to the device, the electrochromic ...
