Abstract

This invention provides an iron-nickel composite carbon fiber material and its preparation method. The iron-nickel composite carbon fiber material comprises: oxygen-modified carbon fibers with oxygen-containing functional groups on their surface; nano-nickel particles distributed on the surface of the oxygen-modified carbon fibers; and an iron-nickel alloy layer coating the oxygen-modified carbon fibers containing the nano-nickel particles. The iron-nickel composite carbon fiber material provided by this invention, by incorporating nano-nickel particles between the oxygen-modified carbon fibers and the iron-nickel alloy layer, enhances the magnetic permeability of the iron-nickel composite carbon fiber material. The oxygen-containing functional groups on the surface of the oxygen-modified carbon fibers can anchor metal ions, improve the uniformity of the nano-nickel particle distribution, and enhance the interfacial bonding force between the nano-nickel particles, the iron-nickel alloy layer, and the carbon fibers.
