Abstract

The invention provides a functional cellulose fiber containing graphene. The functional cellulose fiber containing the graphene is obtained by mixing graphene dispersion liquid with a cellulose spinning solution to prepare a graphene / cellulose spinning solution and then subjecting the graphene / cellulose spinning solution to wet spinning, wherein mass content of the graphene, in the graphene / cellulose spinning solution, accounting for Alpha cellulose in the graphene / cellulose spinning solution ranges from 2.0% to 6.0%. The invention further provides a preparation method of the functional cellulose fiber containing the graphene. In the graphene / cellulose spinning solution prepared by the method, uniformity in dispersion and difficulty in agglomeration of the graphene are achieved. According to the method, the step that oxidized graphene is reduced by a reducing agent in a follow-up process is omitted, so that fiber performance is improved. Content of the graphene in the functional cellulose fiber containing the graphene is 2.0-6.0%. The functional cellulose fiber containing the graphene is uniform in graphene distribution, high in temperature rise rate, excellent in far-infrared and anti-ultraviolet performance and better in thermal stability performance.

Description

technical field [0001] The invention relates to a graphene-functionalized cellulose fiber and a preparation method thereof. Specifically, a flexible online adding device is used to realize uniform dispersion of graphene in a cellulose solution, and is applied to prepare graphene-functionalized cellulose fibers. It belongs to the field of textile technology. Background technique [0002] Graphene is a planar film composed of carbon atoms in a hexagonal honeycomb lattice with sp2 hybrid orbitals. It is a new material with a two-dimensional single-layer sheet structure with a thickness of only one carbon atom. It has excellent electrical conductivity, thermal conductivity and Mechanical properties, thus becoming an ideal functional filler for the preparation of functional polymer composites. [0003] Viscose fiber is similar to cotton fiber in performance, comfortable to wear, has good hygroscopicity and dyeability, and has advantages that other chemical fibers cannot match. ...
