Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventors believe that as the number of migrations of lithium ions between the ion-conducting layer and the electrochromic layer increases, a part of lithium ions will gradually block the ions between the ion-conducting layer and the electrochromic layer. The transmission channel weakens the ability of tungsten oxide to absorb lithium ions, resulting in a decrease in the color adjustment range of the color-changing device as the usage time increases

[0039] Preparation Example of Porous Glass Beads

[0040] The following takes preparation example 1 as an example for illustration.

preparation example 1

[0042] The raw materials used in this preparation example can all be obtained from the market. Among them, the glass beads are SOVITEC solid glass beads produced by Kunshan Chuanlinwei Trading Co., Ltd.; the hydrochloric acid is chemically pure 37% Concentrated hydrochloric acid (CP grade) prepared. Porous glass microspheres were prepared as follows:

[0043] (1) Put the glass beads into the crucible, heat at 450-600° C. for 40 h, and cool the glass beads at a cooling rate of 20° C. / min after the heating;

[0044] (2) Put the glass microspheres cooled to room temperature into 2mol L -1 Pickling in a hydrochloric acid solution, pickling for 1.8h, taking out the glass beads for washing and drying, to obtain porous glass beads.

preparation example 2-6

[0046] As shown in Table 1, the difference between Preparation Examples 2-6 and Preparation Example 1 is that the cooling rate is different.

Abstract

The invention relates to the technical field of glass products, and particularly discloses an intelligent dynamic dimming film and a preparation method and application thereof. The intelligent dynamic dimming film is prepared from the following raw materials in parts by weight: 30-50 parts of porous glass beads, 10-18 parts of lithium hydroxide, 20-40 parts of nano tungsten trioxide, 6-12 parts of polypyrrole, 40-60 parts of silica sol and 5-10 parts of a silane coupling agent. The stability of the color change adjusting range of the intelligent dynamic light adjusting film can be improved favourably.

Description

technical field [0001] The present application relates to the technical field of glass products, more specifically, it relates to an intelligent dynamic dimming film and its preparation method and application. Background technique [0002] Electrochromic glass is a new type of functional material, which is usually assembled by a glass substrate and an electrochromic layer. The main component of the electrochromic layer is an electrochromic material (usually a transition metal oxide). Electrochromic materials have the characteristic of changing color under the action of electric current. With this characteristic, electrochromic glass can adjust its own light transmittance and light absorption under the control of electric current, so as to achieve the effect of adjusting indoor brightness. [0003] The Chinese patent with the notification number CN103365017B discloses an inorganic all-solid-state electrochromic device, including a glass substrate and a transparent conductive ...
