Abstract

The invention discloses an electrochromic fiber and a preparation method thereof. The electrochromic fiber comprises an electrode and a substrate. The electrode comprises at least one pair of electrode wires arranged in parallel. The electrodes are arranged in the substrate. The electrochromic fiber further comprises a liquid crystal material. The substrate comprises at least one pore-like structure parallel to the electrode wires. The liquid crystal material is filled in the pore-like structure of the substrate. According to the invention, the electrochromic fiber based on the electric fieldexcited liquid crystal material is obviously superior to light and temperature in regulation; the good controllability thereof and flexibility have great application advantages in flexible display such as flexible sensing and smart wear; the electrochromic fiber based on the liquid crystal material is prepared by a hot drawing process; and the electrochromic fiber has the advantages of high production efficiency and mass production.

Description

technical field

[0001] The invention relates to the field of functional fibers, in particular to an electrochromic fiber and a preparation method thereof. Background technique

[0002] The liquid crystal material has a one-dimensional or two-dimensional ordered structure. The orientation of this ordered structure can lead to a change in the refractive index of the liquid crystal material to light under the action of temperature, electric field or light (realize the Bragg reflection of incident light), resulting in It shows bright colors under the irradiation of visible light. At present, liquid crystal materials are mainly used in many aspects such as electronic labels, e-books, smart cards, flat-panel displays, large advertising billboards and handwriting computers. The main limitation is that the two-dimensional rigid plane is constructed. , unable to meet the needs of some fields (such as flexible sensing, smart wearable).

[0003] There are many sources of color-changin...
