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 washing fastness is weak

Abstract

The invention discloses a graphene oxide / chitosan / silver nanowire functional cotton fiber and a preparation method thereof. A cationized cotton fabric is obtained through modifying a cotton fabric byvirtue of sodium hydroxide, trimethylallylammonium chloride and PAMAM (polyamidoamine), and then is sequentially impregnated in a hydroxyl-terminated hyperbranched polymer modified silver nanowire solution and a graphene oxide-chitosan mixed solution, and the graphene oxide / chitosan / silver nanowire functional cotton fiber is finally obtained by self-assembly. Graphene oxide / chitosan and a silver nanowire are self-assembled and firmly bonded layer by layer by virtue of an electrostatic force, and the cotton fiber is endowed with high performance of conductivity, antibacterial performance, antiultraviolet performance and the like, and has high application value in the fields of textile, clothes, wearable equipment, flexible conductive devices and the like.

Description

technical field [0001] The invention relates to a graphene oxide / 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 r...
