Problems solved by technology

In addition, graphene prepared by the redox method can be uniformly dispersed in water and organic solvents, and has strong operability, which is beneficial to the preparation of graphene / polymer composites; however, during the acidification and oxidation of graphite, each graphite layer The crystal regularity is destroyed, which greatly affects its electrical conductivity and mechanical properties.
So far, it is difficult to prepare reduced graphene oxide materials with a carbon-to-oxygen ratio higher than 15:1, which will cause a partial loss of its electrical conductivity and mechanical properties, preventing it from becoming an ideal electrical conductor and enhancing fillers to prepare polymers for electrical conductivity. composite material

Abstract

The invention discloses a formula for producing conductive fiber through graphene. The formula for producing conductive fiber through graphene comprises the following components: (1) graphene with the addition amount of 0.1-5% vol; (2) a solvent; (3) polyphenylene sulfide with the addition amount of 5-20% in percent by mass.

Description

technical field [0001] The invention relates to the field of conductive polymer composite materials, in particular to a formula for producing conductive fibers from graphene. Background technique [0002] Graphene is a honeycomb two-dimensional crystal structure material formed by sp2 hybridized carbon atoms. It is only one atom thick, and the single layer thickness is only 0.3nm. The thermal conductivity is 3800~5000 W / (m·K) , the Young's modulus is 1TPa, and the breaking strength is 130GPa; due to the above-mentioned excellent mechanical and functional properties of graphene, adding it to the polymer matrix as a reinforcing and conductive filler can effectively improve the properties of the polymer. Therefore, research on graphene has become a hot spot in the field of conductive polymer composite materials; [0003] Polymer conductive nanocomposites have wide application potential in the fields of aerospace, electronics, electric power and new energy. However, most of th...
