Embodiment 1

[0036] The structure of the electrochromic material of the present invention is that NiO thin film is deposited on an ITO substrate, WO 3 -PANI composite film is deposited on another ITO substrate; solid mixed polyelectrolyte is set on NiO film and WO 3 - between the PANI composite films, and both ends of the solid mixed polyelectrolyte are encapsulated in the NiO film and WO 3 - between PANI composite films.

Embodiment 2

[0038] The preparation method of the electrochromic material structure of the present invention is implemented according to the following steps:

[0039](1) 0.16 mol of nickel sulfate, 0.03 mol of potassium persulfate and 400 ml of water were magnetically stirred and mixed uniformly to prepare a dark green solution. Tape polyimide tape on the non-conductive side of the ITO to prevent deposition on this side. The ITO was vertically placed in the solution, and 40 mL of ammonia water was added to the solution, stirred vigorously, a film was deposited, and washed with ultrapure water. The tape was removed, the sample was dried in an oven, and then air annealed at 300 °C for 1.5 h to prepare a NiO film.

[0040] (2) 5mL of 0.1M dilute sulfuric acid solution and aniline solution were magnetically stirred and mixed evenly, and 2mL of 0.1M sodium tungstate solution was added thereto to prepare a transparent electrolyte solution. Choose a two-electrode system, two pieces of ITO are u...

Embodiment 3

[0044] The smart window double as a supercapacitor of the present invention includes a frame, a slide and a window body; the structure of the window body is formed by arranging an electrochromic material structure between two glass sheets. Connect the voltage control system and each smart window in parallel to test the electrochromic performance and capacitor performance of the smart window.

Abstract

The invention discloses an electrochromic material structure, a preparation method and an intelligent window thereof. According to the electrochromic material structure, an NiO film is deposited on an ITO (Indium Tin Oxide) substrate, and a WO3-PANI composite film is deposited on another ITO substrate; a solid mixed polyelectrolyte is arranged between the NiO film and the WO3-PANI composite film, and the two ends of the solid mixed polyelectrolyte are both packaged between the NiO film and the WO3-PANI composite film with resin; the structure of an intelligent window body is formed by setting the electrochromic material structure between two glass sheets. The electrochromic material structure used by the intelligent window is selected, so that the intelligent window has the performance of a supercapacitor; the intelligent window can track the energy of incident light for adjustment so as to control the indoor temperature, and can also realize the storage and release for electric charges. The structure is safe and efficient, energy-saving and environment-friendly and long in service life.

Description

technical field [0001] The invention belongs to the technical field of electrochromic materials, and in particular relates to an electrochromic material structure, a preparation method thereof and an intelligent window. Background technique [0002] Electrochromism means that under the action of a certain electric field or current, the material will scatter or absorb light, which will cause its color to change. When the polarity of the electrode changes, it will fade again. Since Deb.S.K. first discovered WO in 1969 3 Since the phenomenon of electrochromism, people have discovered many 3 Substances that also have electrochromic properties, such as NiO, viologen, polyaniline, etc., have gradually increased the types of electrochromic materials and their applications have gradually become wider. [0003] Because electrochromic materials can control light energy and reduce energy loss, which is in line with the development trend of future smart materials, they have received m...
