Problems solved by technology

[0006] Cellulose fiber itself has good mechanical properties and hygroscopicity, but it does not have functionality
The traditional functional cellulose fibers are mainly realized by post-treatment on the fiber surface, and the functional fibers prepared by this method are not washable, and the pollution caused by post-treatment is relatively serious, so the application of cellulose fibers is limited. certain limit

Abstract

The invention discloses a graphene anion regenerated cellulose composite fiber and a preparation method thereof. The method comprises the following steps of step 1, weighing raw materials in proportion, wherein the raw materials comprise cellulose, a graphene material, a modifier and negative ion powder; step 2, grinding the negative ion powder by using a ball mill, and then drying; step 3, dispersing the cellulose, the graphene and the modifier in a solvent, and stirring to fully dissolve the cellulose to prepare a spinning solution; and step 4, spinning the spinning solution containing the completely dissolved cellulose obtained in the step 3 by using a dry-jet wet spinning process. The invention also provides the graphene anion regenerated cellulose composite fiber prepared by the method. According to the graphene anion regenerated cellulose composite fiber and the preparation method thereof provided by the invention, the prepared composite fiber has the functions of resisting bacteria, releasing anions and the like, and the application range of the cellulose fiber can be expanded.

Description

technical field [0001] The invention relates to a graphene composite fiber and a preparation method thereof, in particular to a graphene negative ion regenerated cellulose composite fiber and a preparation method thereof. Background technique [0002] Graphene is a single-layer carbon atom material peeled off from graphite. Carbon atoms are tightly packed into a single-layer two-dimensional honeycomb lattice structure. It is the thinnest, hardest, and best-conducting material known to mankind. Material. Graphene has excellent mechanical, optical and electrical properties, and its structure is very stable. So far, researchers have not found the absence of carbon atoms in graphene. The links between carbon atoms are very flexible, harder than diamonds, and stronger than the world's The best steel is 100 times higher. If you use graphene to make a packaging bag, it will be able to bear about two tons of items, almost completely transparent, but extremely dense, impermeable, ai...
