Chemical bath method for depositing electrochromism membrane

Abstract

The invention discloses a chemical bath method for depositing an electrochromism membrane. The chemical bath method comprises the following steps: providing nickel sulfate and potassium persulfate, and preparing a precursor liquid of the nickel sulfate and the potassium persulfate; treating the prepared precursor liquid so as to increase the pH value of the precursor liquid; providing ammonium hydroxide, and mixing the treated precursor liquid with the ammonium hydroxide so as to obtain a mixed solution; providing FTO (fluorine-doped tin oxide) glass or ITO (indium tin oxide) glass to be plated, and soaking the FTO glass or the ITO glass to be plated into the mixed solution; taking out the plated FTO glass or the ITO glass, performing drying, and further wiping off nickel oxide deposited on the back side of the FTO glass or the ITO glass by using dilute sulfuric acid; and annealing the plated FTO glass or the ITO glass for 2-5 hours at 100-500 DEG C so as to obtain the FTO glass or theITO glass plated by the electrochromism membrane, wherein the electrochromism membrane is nickel oxide. By adopting the chemical bath method for depositing the electrochromism membrane, hydrolysis ofpersulfate can be inhibited, so that an oxygen source can be prevented from being consumed in an oxygen mode, and thus membrane deposition can be 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...
