Embodiment 1

[0061] see Figure 5 , the fiber electrochromic device of the winding structure of the present embodiment has two conductive fibers 21' and 22', wherein, the conductive fiber 21' is a tin wire with a diameter of 6mm, and its surface is covered with a layer prepared by magnetron sputtering. WO 3 The thin film is used as an electrochromic thin film; the conductive fiber 22' is a copper wire with a diameter of 6 mm exposed on the surface.

[0062] Such as Figure 5 (a) and Figure 5 As shown in (b), apply a voltage from the conductive fiber 22' to the conductive fiber 21', the voltage is 0.5V-3V, and the loading time is 1s-300s, then it can be observed that the surface of the conductive fiber 21' is colored, However, the surface color of the conductive fiber 22' remains unchanged.

Embodiment 2

[0064] see Image 6, in this embodiment, the fiber electrochromic device of the winding structure of this embodiment has two conductive fibers 21 "and 22 ", wherein, said conductive fiber 21 " is the tin wire of diameter 6mm, and its surface is covered with through WO prepared by magnetron sputtering 3 film, as an electrochromic film; similarly, the conductive fiber 22 "is a tin wire with a diameter of 6 mm, and its surface is covered with WO prepared by magnetron sputtering. 3 film, as an electrochromic film.

[0065] Such as Image 6 (a)- Image 6 (d) shown. Apply a voltage from the conductive fiber 21" to the conductive fiber 22", the voltage ranges from 0.5V to 3V, and the loading time is 1s to 300s, then it can be observed that the surface of the conductive fiber 22' is colored, but the surface of the conductive fiber 21" is not colored. coloring.

Abstract

The invention relates to a fiber electrochromic device with a winding structure, the fiber electrochromic device sequentially includes insulating fibers, at least two conductive fibers, an electrolyte layer and an insulating packaging layer from the inside to the outside, and the conductive fibers are not in contact with each other , and helically wound on the surface of the insulating fiber in parallel, wherein the surface of at least one conductive fiber is covered with an electrochromic film. The invention also relates to the application of the fiber electrochromic device in intelligent clothing and wearable static displays. The fiber electrochromic device with winding structure does not need to be packaged with transparent and soft conductive materials, and can realize multi-color display and diversified display.

Description

technical field [0001] The invention relates to the field of electrochromism, in particular to a fiber electrochromic device with a winding structure and its application. Background technique [0002] With the development of society and the improvement of people's living standards, consumers have put forward higher requirements for textiles, among which color-changing fabrics and wearable static displays have become the emerging development directions of the consumer market. According to the different external stimuli that cause the material to change color, the discoloration phenomenon is generally divided into the following categories: thermochromism, photochromism, electrochromism, piezochromism, humidity-sensitive discoloration, solvent-induced discoloration, etc. Among them, electrochromic has the characteristics of self-regulation and fast response time, so it is favored by the majority of scientific researchers, and is more easily accepted by manufacturers and consume...
