Embodiment 1

[0038] An electrochromic device, including a 0.15mm thick high-transparency glass, a 200nm thick ITO conductive layer, a 150μm thick polyaniline electrochromic layer, a 50μm thick PVB / lithium perchlorate electrolyte layer, and a 150μm thick Prussian blue ion layer, which are stacked in sequence Storage layer, 200nm thick ITO conductive layer and 0.15mm thick high transparency glass.

[0039] The specific preparation method of the electrochromic device is as follows:

[0040] Clean the 0.15mm thick high-transparency glass and put it into the magnetron sputtering chamber, and vacuum the equipment to 5×10 -4 -5×10 -3 Pa, and then argon gas was introduced until the vacuum degree reached 0.5 Pa, and a 200nm ITO conductive film was magnetron sputtered at 350°C using an intermediate frequency power supply.

[0041] After the sputtered ITO conductive film is taken out and cooled, it is placed on a scraper coating device, and a 150 μm thick scraper is used to scrape a polyaniline fil...

Embodiment 2

[0045] An electrochromic device, including a 0.10mm thick PET / ITO conductive film, a 100μm thick violet electrochromic layer, a 50μm thick lithium perchlorate / propylene carbonate electrolyte layer, and a 100μm thick PEDOT:PSS ion layer Storage layer, 0.10mm thick PET / ITO conductive film.

[0046] The specific preparation method of the electrochromic device is as follows:

[0047] Wash the 0.1mm thick PET / ITO high-transparency conductive film and place it on the scraping equipment, adjust the thickness of the scraping to 100 μm, and scrape the Pedot:PSS slurry. Take out the scraped PEDOT:PSS conductive film and dry it. Scrape-coat viologen film on another PET / ITO high-transmittance conductive film. After scraping, the viologen film was placed in a vacuum oven, and the residual solvent on the surface was evaporated at 110°C to make it solidify on the PET conductive film.

[0048] Subsequently, drop lithium perchlorate / propylene carbonate / UV glue on the surface of viologen, us...

Embodiment 3

[0051] An electrochromic device, including a 0.15mm thick high-transmittance ITO conductive glass, an electrochromic layer of diethyl 4,4-biphenyldicarboxylate, and an electrolyte layer / ion storage of ferrocene / lithium chloride Layer, 0.10mm thick PET / ITO high transparent conductive film.

[0052] The specific preparation method of the electrochromic device is as follows:

[0053] The 0.15mm thick high-transparency ITO conductive glass and the 0.1mm thick PET / ITO high-transmission conductive film are used as symmetrical conductive substrates, and 4,4-biphenyl diethyl ester is spin-coated on the ITO conductive glass surface. After drying in an oven at ℃, glue is then dispensed on the surface, and after bonding with PET / ITO conductive film, it is cured into a sealed open box of 1000mm×1000mm, and ferrocene and lithium chloride solution are injected into the box as electrolyte, and then the The sealed open box is sealed and cured.

[0054] The functions of yellow and yellow-der...

Description

technical field [0001] The invention relates to the field of electrochromism, in particular to an electrochromic device, a preparation method thereof, and an electronic product. Background technique [0002] Electrochromism refers to a series of reversible changes in the optical properties in the visible wavelength range caused by the oxidation or reduction of materials under the action of DC voltage. From the appearance point of view, it is a reversible change in color and transparency. In 1961, Deb discovered for the first time that tungsten trioxide thin films could switch between colorless and blue under the action of an electric field. Based on this discovery, the scientists proposed a new concept of smart electrochromic windows. Since then, the preparation of electrochromic materials and their devices has attracted the attention of many researchers. Generally, we refer to materials with electrochromic properties as electrochromic materials, and devices made of elect...
