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 nano zinc oxide / silver nanowire multifunctional cotton fiber and a preparation method thereof. The preparation method includes: using sodium hydroxide, trimethylallylammoniumchloride and PAMAM to modify a cotton fabric to obtain a cationic cotton fabric, then impregnating the cationic cotton fabric in a hydroxyl terminated hyperbranched polymer modified silver nanowire solution and a nano zinc oxide solution in order for self-assembly, thus finally obtaining the nano zinc oxide / silver nanowire multifunctional cotton fiber. Silver nanowires and nano zinc oxide undergolayer-by-layer self-assembly to combine firmly, and endow the cotton fiber with excellent conductive, antibacterial, anti-ultraviolet and other properties. The nano zinc oxide / silver nanowire multifunctional cotton fiber prepared according to the invention has important application value in textile, clothing, wearable devices, flexible conductive devices and other fields.

Description

technical field [0001] The invention relates to a nano-zinc oxide / silver nano-wire multifunctional cotton fiber, which belongs to the field of nano-composite 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 resear...
