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, the interaction between AgNWs and cotton fibers in the above literature 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 (Chemical Progress, 2017, 29(8 ): 892-901)

Abstract

The invention discloses PEDOT:PSS / chitosan / silver nano-wire functionalized cotton fiber and a preparation method thereof. The preparation method comprises the following steps: modifying cotton fabricwith sodium hydroxide, trimethylallylammonium chloride and PAMAM to obtain cationized cotton fabric, dipping the cationized cotton fabric into a silver nano-wire solution modified with a hyperbranchedpolymer with terminal hydroxyl and a PEDOT:PSS-chitosan mixed solution sequentially, and performing layer-by-layer self-assembling to finally obtain the PEDOT:PSS / chitosan / silver nano-wire functionalized cotton fiber. The PEDOT:PSS-chitosan and the silver nano-wire are firmly combined through electrostatic attraction layer-by-layer self-assembling, the cotton fiber is endowed with excellent electroconductive, antibacterial and anti-ultraviolet properties, and important application value is achieved in the fields of textile, clothes, wearable equipment, flexible electroconductive devices and the like.

Description

technical field [0001] The invention relates to PEDOT:PSS / chitosan / silver nanowire functionalized cotton fiber, which belongs to the field of nanocomposite 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 research...
