Problems solved by technology

For example: (1) Cotton fiber has the characteristics of large specific surface area and strong moisture absorption capacity, so it is easy to attach, reproduce and spread microorganisms during consumption, which will cause the strength of cotton fiber to decrease, produce stains, fade and smell, and even spread diseases and affect the human body healthy
(2) Excessive ultraviolet radiation can cause skin damage, aging, and even cancer
However, in the above literature, the interaction between AgNWs and fibers is mainly based on physical adsorption in the form of van der Waals force and hydrogen bonds, lacking a firm force combination, and its wash fastness is weak (electronic textiles based on silver nanowire conductive network , Advances in Chemistry, 2017, 29(8): 892-901)

Abstract

The invention discloses conductive polymer coated silver nanowire conductive cotton fiber, which is prepared by the following steps: performing anionic modification of cotton fiber; performing layer-by-layer self-assembly of a silver nanowire and a high molecular conductive polymer PEDOT:PSS on the surface of the anionic cotton fiber to finally obtain PEDOT:PSS coated silver nanowire conductive cotton fiber. The silver nanowire and the PEDOT:PSS give the cotton fiber excellent performance in conductivity, bacteria resistance, ultraviolet resistance and washing fastness; the cotton fiber has important application value in the fields such as wearable equipment and flexible conductive devices.

Description

technical field [0001] The invention relates to a silver nanowire conductive cotton fiber wrapped by a conductive polymer, which belongs to the field of textile materials. Background technique [0002] Cotton fiber is loved by consumers for its excellent properties such as moisture absorption, breathability, comfort, softness, warmth retention, renewable and degradable. However, compared with synthetic fibers, the functionality of cotton fibers is still insufficient. For example: (1) Cotton fiber has the characteristics of large specific surface area and strong moisture absorption capacity, so it is easy to attach, reproduce and spread microorganisms during consumption, which will cause the strength of cotton fiber to decrease, produce stains, fade and smell, and even spread diseases and affect the human body healthy. (2) Excessive ultraviolet radiation can cause skin damage, aging, and even canceration. (3) In recent years, conductive textiles have gradually become a res...
