specific Embodiment approach 1

[0041] Embodiment 1: In this embodiment, the preparation method of the glass substrate silver / polyaniline electrochromic film is carried out according to the following steps:

[0042] 1. The pretreated silver flake with a purity of 99.7% is used as the target material, and the cleaned glass flake is used as the base. The glass flake is placed directly above the silver flake. The distance is 5 μm, and the vertical targeting pulse laser method is used to scan the target material under the conditions of a laser beam with a wavelength of 1064 nm, a pulse laser output power of 10W-25W, and a deposition number of 1-20 times at room temperature and in an argon atmosphere. Silver flakes to obtain glass flakes with silver nano-films, namely glass substrates / silver nano-films;

[0043] 2. Add 26.0ml of hydrochloric acid with a mass concentration of 37% to 174.8ml of distilled water to obtain dilute hydrochloric acid; dissolve 45.6g of ammonium persulfate with 100ml of dilute hydrochlori...

Abstract

The invention discloses a preparation method of a glass-substrate / silver nano-film / polyaniline electrochromic film, relates to a preparation method of electrochromic films, and solves the technical problems that electrochromic devices are high in preparation cost because of taking ITO (indium tin oxide) glass as a conductive substrate, and the existing method is poor in uniformity of prepared metal films and complex in operation. The method comprises the following steps: 1, preparing a glass sheet to which a silver nano film is attached; 2, preparing a polyaniline (PANI) solution; and 3, vertically inserting the glass sheet to which the silver nano film is attached into the PANI solution, dipping 30 minutes, sequentially washing the glass sheet by using deionized water and a dilute hydrochloric acid, and carrying out natural airing on the glass sheet, thereby obtaining the glass-substrate / silver nano-film / polyaniline electrochromic film. The silver nano-film prepared by using the method disclosed by the invention is good in uniformity and electrical conductivity, and the color conversion effect of the glass-substrate / silver nano-film / polyaniline electrochromic film is better than that of an ITO / PANI film. The method disclosed by the invention belongs to the preparation field of electrochromic films.

Description

technical field [0001] The invention relates to a preparation method of an electrochromic film. Background technique [0002] Electrochromism is a kind of color change with changeable optical properties, which generally refers to the reversible color change of a material under the action of an external electric field or current, which is intuitively manifested as a process in which the color and transparency of the material change reversibly. Since the concept of electrochromism was first proposed by foreign scholar Plant in the 1960s, the phenomenon of electrochromism has attracted extensive attention. Using this electrochromic phenomenon, electrochromic devices can be fabricated. Electrochromic devices have unique advantages such as wide viewing angle, low driving voltage, and no power consumption memory, so they are widely used in sensitive windows, displays, and rearview mirrors of automobiles. Since the development of electrochromic devices, the structure generally ac...
