Problems solved by technology

At present, the common regenerated cellulose fibers are mainly viscose fibers and Russell fibers. Because the cellulose dissolution methods used in these two processes cannot effectively disperse nanomaterials, the preparation of regenerated cellulose composite fibers is limited to a certain extent.

Abstract

The invention relates to a novel cellulose / hydroxylated multiwalled carbon nanotube / Fe3O4 nano-particle composite fiber and a preparation method thereof. The composite fiber comprises, by weight, 89.6-99.45 parts of cellulose, 0.5-10 parts of hydroxylated multiwalled carbon nanotubes and 0.05-0.4 part of Fe3O4 nano-particles. The fiber is prepared from the raw materials through a solvent method. By means of the method, the hydroxylated multiwalled carbon nanotubes can be dispersed, furthermore, cellulose can be dissolved at the normal temperature, the preparation condition is mild, and the procedure is simple and convenient. According to the composite fiber and the preparation method thereof, the hydroxylated multiwalled carbon nanotubes and the Fe3O4 nano-particles are made to uniformly adhere into cellulose through electrostatic force and hydrogen bonds, the obtained regenerated cellulose composite fiber is stable in performance and homogeneous in texture, compared with traditional regenerated cellulose fibers, the strength is higher, meanwhile, electrical conductivity and magnetic performance are achieved, and the fiber can be used as a degradable fiber to be applied to multiple fields.

Description

technical field [0001] The invention belongs to the field of composite materials, and relates to a cellulose / hydroxylated multi-walled carbon nanotube / Fe 3 o 4 Nanoparticle composite fiber and its preparation method. Background technique [0002] Regenerated cellulose fiber is a common bio-based degradable fiber. Due to its wide source of materials and its ability to be regenerated, it has attracted more and more attention with the improvement of people's awareness of environmental protection. Regenerated cellulose fiber is currently widely used in various textiles, tire cords, conveyor belts and other industrial products. However, due to the low strength and single function of regenerated cellulose fiber, its use is also limited. At present, many studies have focused on the development of Regenerated cellulose fibers with special functions and excellent properties, among which, the use of nanoparticles and cellulose blends to prepare regenerated cellulose materials has ma...
