Problems solved by technology

These two electrochromic fibers do not use an ion storage layer. Although the structure is simple, during use, due to the lack of an ion storage layer, lithium ions will directly impact the conductive layer when fading, resulting in poor durability of the fiber. Poor wearing experience, difficult to apply in the textile market and wearable static display

Embodiment 1

[0028] see figure 1 with figure 2 , figure 1 It is a structural schematic diagram of the coaxial electrochromic fiber of the present embodiment, figure 2 It is a schematic diagram of the hierarchical structure of the electrochromic fiber with coaxial structure peeled off layer by layer in this embodiment. The electrochromic fiber of the coaxial structure includes a conductive support fiber 1 , a transparent transition layer 2 , a color-changing layer 3 , an electrolyte layer 4 and a conductive high polymer coating layer 5 sequentially from inside to outside.

[0029] In this embodiment, the conductive support fiber 1 is a light-colored material, which can be obtained by interweaving metal-plated fabrics, surface-impregnated conductive polymer fabrics, metal-plated conductive fibers, or pure metal fibers and ordinary fibers. Fabric and pure metal fiber constitute at least one of the fabric, and its surface resistance is preferably 0.01-1000Ω.

Embodiment 2

[0042] This embodiment provides a kind of textile, and it adopts conventional method to weave by the electrochromic fiber of coaxial structure in embodiment 1 and makes, and its working state is as follows Figure 4 shown. The textile has the advantages of long service life and good durability, and can be used in smart clothing and wearable static displays.

[0043] Compared with the prior art, the electrochromic fiber of the coaxial structure of the present invention is based on the axial migration of ions in the color-changing layer under the drive of the working voltage to switch between coloring and fading, thereby avoiding the occurrence of ion migration from the color-changing layer. Therefore, in the case of no ion storage layer, this electrochromic fiber also has the advantage of good durability, and has a good application prospect in the textile market and wearable static display.

Abstract

The invention relates to an electrochromic fiber with a coaxial structure and application of the electrochromic fiber. The electrochromic fiber with the coaxial structure sequentially includes a conductive support fiber, a discoloration layer, an electrolyte layer and a conductive polymer cladding layer from inside to outside; the conductive polymer cladding layer and the conductive support fiberare connected through a first external circuit so as to provide initialization voltage; the two ends of the conductive support fiber are connected through a second external circuit so as to provide working voltage. In the absence of an ion storage layer, the electrochromic fiber also has the advantages of being good in durability and can be applied to the intelligent clothing field, the wearable static display field and other fields.

Description

technical field [0001] The invention relates to the field of electrochromism, in particular to an electrochromic fiber with a coaxial structure and an application thereof. 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 controllable 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 material discoloration, it can generally be divided into the following categories: thermochromism, photochromism, electrochromism, piezochromism, moisture-sensitive discoloration, solvent-induced discoloration, etc. Among them, electrochromism is favored by the majority of scientific researchers due to its characteristics such as self-regulation and fast response time, and is more easily accepted by entrepreneurs and consumers.
