Abstract

The invention discloses conductive graphene fibers. The conductive graphene fibers comprise functional hemp-cotton fibers and graphene fibers, wherein the mass ratio of the functional hemp-cotton fibers to the graphene fibers is 100:(5-10). The conductive graphene fibers have the technical advantages as follows: 1) the conductive graphene fibers have relatively high strength and toughness, and the electrical resistivity is about 10-103 omega.m and is increased by more than ten orders of magnitude than that (about 1,014 omega.m) of common fibers; 2) the conductive fibers are composite of the graphene fibers and the hemp-cotton fibers, and accordingly, fabric produced finally has the characteristics of softness and fineness of cotton, smoothness of hemp and the like.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a graphene conductive fiber. Background technique [0002] Conductive fibers have always been a research hotspot for functional fibers, generally referring to resistivity less than 10 8 The fiber of Ω·cm has the functions of conduction, electric heating and anti-electromagnetic radiation, and is usually concentrated in the fields of anti-static clothing or anti-electromagnetic radiation clothing used in special occasions. [0003] The main methods for the manufacture of conductive fibers include: one is to coat the surface of conventional fibers with conductive components, and the other is to mix conductive materials with fiber raw materials and make conductive fibers by spinning. The method of coating the conductive layer on the surface of the fiber is to coat the conductive material containing metal, carbon black or metal compound on the surface of the fiber to ma...
