Problems solved by technology

[0003] Among them, the importance of color to fibers and fabrics is self-evident. Clothes of different colors make the world more colorful. For traditional dyeing and finishing techniques, dyes of different colors allow us to wear colorful clothes. , but when dyed and formed, the dye on the fiber cannot intelligently change the color, which limits the application of the fiber in more fields, so it is very important to develop a functional, intelligent, and relatively energy-saving and environmentally friendly color-changing fiber

Abstract

The invention relates to a preparation method of an electrochromic intelligent fiber. The preparation method of the electrochromic intelligent fiber comprises the following steps: dissolving 3,4-ethylenedioxythiophene in lithium perchlorate propylene carbonate solution to obtain a deposition solution, then vertically placing a stainless steel fiber subjected to ultrasonic washing into the deposition solution for carrying out electrolytic deposition, performing vacuum drying, so that the stainless steel fiber coated with poly(3,4-ethylenedioxythiophene) (PEDOT) is obtained; dipping gel electrolyte on the stainless steel fibers coated with PEDOT, drying at room temperature, then winding another stainless steel fiber on the stainless steel fiber dipped with the gel electrolyte, dipping the gel electrolyte again, and drying at room temperature, so that the electrochromic intelligent fiber is obtained. The preparation method of the electrochromic intelligent fiber is simple, low in cost and applicable to large-scale production; the prepared electrochromic intelligent fiber has good optical property, high transformation speed, good flexibility and obvious gradient effect.

Description

technical field [0001] The invention belongs to the field of preparation of color-changing fiber materials, in particular to a preparation method of electrochromic smart fibers. Background technique [0002] After thousands of years of development, fiber products have become an indispensable part of people's daily life, from the earliest natural cotton and linen silk, to the emergence of synthetic fibers in the 19th century, and now the rapid development of the chemical fiber industry, During this process, a series of synthetic fiber varieties with special properties have been developed, and the application fields of chemical fibers have been continuously expanded. However, the existing fibers have limited functions, which greatly limit the application of fibers in more fields. This requires us to give it more functions besides the traditional mechanical properties. In recent years, a lot of research has focused on fibrous devices and materials and their application on fabr...
