Abstract

The invention discloses an electrochromic fiber and a preparation method thereof. The electrochromic fiber includes an electrode and a base material, and the electrode includes at least a pair of electrode wires arranged in parallel, and the electrode wires are arranged on the base material. In addition, the electrochromic fiber also has a liquid crystal material, the substrate has at least one pore-like structure parallel to the electrode wire, and the liquid crystal material is filled in the pore-like structure of the substrate. The color-changing fiber based on the liquid crystal material excited by the electric field provided by the present invention is obviously superior to light and temperature in terms of regulation, and its good controllability and flexibility have great application advantages in flexible displays such as flexible sensing and smart wear. The electrochromic fiber based on the liquid crystal material is prepared by a thermal stretching process, which has high production efficiency and can be produced on a large scale.

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...
