Embodiment Construction

[0027] Specific embodiments of the present invention will be further described in detail below. It should be understood that the description of the embodiments of the present invention here is not intended to limit the protection scope of the present invention.

[0028] Such as figure 1 As shown, it is a flow chart of the chemical bath method for depositing an electrochromic thin film provided by the present invention. The chemical bath method of the deposition electrochromic thin film comprises the steps:

[0029] STEP1: provide nickel sulfate and potassium persulfate, and mix the nickel sulfate and potassium persulfate to prepare the precursor solution of nickel sulfate and potassium persulfate;

[0030] The nickel sulfate is an inorganic substance, which is the source of metal nickel ions, and can dissociate nickel ions and sulfate ions during the reaction process. The potassium persulfate is also an inorganic compound and is a white crystal. The persulfate in the potas...

Abstract

A chemical bath method for depositing an electrochromic thin film, comprising the steps of: providing nickel sulfate and potassium persulfate to prepare a precursor solution of nickel sulfate and potassium persulfate; treating the prepared precursor solution to increase the pH value of the precursor solution Provide ammonia water, mix the treated precursor solution with ammonia water to make a mixed solution; provide FTO glass or ITO glass to be plated, soak the FTO glass or ITO glass to be plated in the mixed solution; coat the FTO glass or the ITO glass is taken out and dried, and then the nickel oxide deposited on the back of the FTO glass or ITO glass is wiped off with dilute sulfuric acid; The FTO glass or ITO glass of the electrochromic film, the electrochromic film is nickel oxide. The chemical bath method for depositing electrochromic thin films provided by the invention can inhibit the hydrolysis of persulfate radicals so as to avoid the consumption of oxygen sources in the form of oxygen, thereby making the deposition of thin films more uniform and controllable.

Description

technical field [0001] The invention belongs to the technical field of electrochromism, in particular to a chemical bath method for depositing electrochromic thin films. Background technique [0002] At present, most color-adjustable sunglasses use photochromic materials. However, the transition between the transparent state and the colored state of the photochromic lens takes 5 minutes or more, and it is artificially uncontrollable, resulting in a poor user experience. Therefore, the electrochromic material with faster discoloration and artificial control provides better technical support for the discoloration lens. Moreover, the electrochromic material can also be triggered by light to change color by embedding a photoresistor, realizing two modes of manual control and automatic control. Electrochromic materials are also used in some other fields. For example, the use of electrochromic materials on smart windows can automatically block heat, thereby reducing the energy c...
