Problems solved by technology

In the patent, strong alkali is used to corrode the fiber surface, which can improve the roughness of the fiber surface to a certain extent, but for fibers with strong alkali resistance such as nylon and polypropylene, the use of strong alkali corrosion cannot form an effective sufficient corrosion resistance on the fiber surface. A large amount of concave-convex anchor points, so that the metallic silver layer cannot be firmly combined with the fiber

Abstract

The invention relates to the field of fiber materials, in particular to an electric and thermal conductive polymer fiber and a preparation method thereof. The electric and thermal conductive polymer fiber comprises a surface layer and a core layer, wherein the core layer is mainly prepared from a molten polymer resin; the surface layer is mainly prepared from a molten mixture of nano-grade graphene, calcium carbonate and a polymer resin; the outer surface of the surface layer is covered by a conductive metal layer. According to the electric and thermal conductive polymer fiber provided by the invention, graphene and calcium carbonate powder are added into the fiber surface layer, so that the graphene and the calcium carbonate powder protrude from the surface of the fiber, the surface roughness of the fiber is improved, and the anchoring points on the surface of the fiber are increased; as the surface of the surface layer is covered by the conductive metal layer, a metal silver is firmly combined with the surface of the fiber, the content of the metal silver on the surface of the fiber is increased, and furthermore the surface resistivity of the fiber is greatly reduced.

Description

technical field [0001] The invention relates to the field of fiber materials, in particular to a conductive and thermally conductive polymer fiber and a preparation method thereof. Background technique [0002] The effective integration of science and technology and the textile industry has made smart textiles mentioned many times by the textile industry recently. Smart textiles are a new trend in the development of textiles and a research hotspot in the 21st century. According to the evaluation of international research institutions, smart textiles, as a high-tech textile, will have a total industry value of 4.7 billion US dollars by 2020. Given that the total value of smart textiles in 2014 was less than $1 billion, the cumulative annual growth rate will reach 30%. The broad prospects of smart textiles have made companies rush to develop products in this area. [0003] Smart textiles are highly intelligent textiles developed comprehensively by applying textiles, electro...
