Method for preparing graphene functionalized alginate fibers

Abstract

The invention discloses a method for preparing graphene functionalized alginate fibers. The method comprises the following steps: firstly adding a defined amount of graphene to a sodium alginate solution to obtain a graphene / alginate spinning solution; or aminating the defined amount of graphene and then ensuring the aminated graphene to covalently bind with sodium alginate through a chemical reaction to obtain a graphene-alginate spinning solution; then ensuring the graphene / alginate spinning solution or the graphene-alginate spinning solution to respectively undergo a coagulation bath to obtain graphene / alginate as-spun fibers or graphene-alginate as-spun fibers; and then drawing, setting and oiling the graphene / alginate as-spun fibers or graphene-alginate as-spun fibers after ensuring the graphene / alginate as-spun fibers or graphene-alginate as-spun fibers to undergo a preheating bath and a drawing bath respectively to obtain graphene / alginate functionalized fibers or graphene-alginate functionalized fibers which are called graphene functionalized alginate fibers. The prepared graphene functionalized alginate fibers integrate the excellent performances of the graphene and the sodium alginate and have the excellent performances such as high tensile strength, good biocompatibility, antistatic performance, light weight, high elasticity, antibacterial performance and the like.

Description

technical field [0001] The invention relates to a preparation method of graphene-functionalized seaweed fiber. Firstly, the non-covalent or covalent combination of graphene and sodium alginate is used to prepare spinning solution, and then the graphene-functionalized fiber is obtained through wet spinning and stretching setting respectively. The invention discloses chemical seaweed fiber, which belongs to the field of chemistry. Background technique [0002] The nano-carbon material graphene appeared in the laboratory in 2004. At that time, two British scientists, Andre Jem and Kostya Novoselov, discovered that they could obtain more thinner and thinner graphite flakes. The appearance of graphene has stirred up huge waves in the scientific community. It has only been 6 years since the successful preparation of graphene materials, and it won the Nobel Prize in 2010. [0003] Graphene is a simple carbon substance composed of carbon atoms arranged in a hexagonal lattice, and ...

AI Technical Summary

Problems solved by technology

At the same time, the development and utilization of seaweed fiber can solve the problems of serious pollution, insufficient raw material sources or high cost in the processing of some recycled fiber products, which is of great significance to promote the sustainable development of the chemical fiber and textile industry

Judging from the development trend at home and abroad and the current status of related technologies, the strength of seaweed fiber is low, so it is limited to the use of medical fibers and cannot be widely used in the field of textile and clothing. The output and application range are very limited.
