Abstract

The invention provides a novel functional graphene composite fiber, and a preparation method and an application thereof. The preparation method comprises the following steps: 1, adding graphene nano-sheets into a molten polymer material, and carrying out melt mixing to uniformly mix the graphene nano-sheets with the polymer material in order to obtain a mixture A, wherein 100 wt% of the mixture A contains 20-30 wt% of the graphene nano-sheets; 2, granulating the mixture A to obtain graphene composite master batches; and 3, carrying out melt mixing and spinning on the graphene composite master batches and the polymer material to obtain the novel functional graphene composite fiber, wherein 100 wt% of the novel functional graphene composite fiber contains 1-4 wt% of the graphene nano-sheets. The invention also provides the novel functional graphene composite fiber prepared through the preparation method. The graphene composite fiber has certain strength, softness and hygroscopicity.

Description

technical field [0001] The invention relates to a novel functionalized graphene composite fiber, a preparation method and application thereof, and belongs to the technical field of composite fiber materials. Background technique [0002] Since the 1950s, the development of chemical fibers has greatly improved the performance and function of textiles, making them fully developed in the fields of clothing, decoration and industry, especially in industries that require high functions of chemical fibers. Due to the development of various synthetic fibers and high-performance, high-function fibers and the realization of their industrial production, their products show a broader development prospect.
