Preparation method for nickel hydroxide/polyether amine modified carbon fiber

The invention discloses a preparation method for nickel hydroxide/polyether amine modified carbon fiber. The preparation method comprises the following steps: cleaning and oxidizing the surface of thecarbon fiber; preparing nickel sulfate hexahydrate, potassium persulfate and deionized water deposition liquor; adopting a chemical-bath deposition method and a soaking method for cleaning and dryingthe carbon fiber by filling deposition liquor and a polyether amine organic solvent solution, thereby accomplishing modification, on the fiber, of the nickel hydroxide/polyether amine. The method sufficiently utilizes excellent electrochemical oxidization-reduction reaction characteristic of nickel hydroxide and an amino group of polyether amine to improve electrochemical performance of the fiber; and meanwhile, a three-dimensional honeycomb structure of the nickel hydroxide and reaction performance of the polyether amine are utilized to improve interface bonding strength of the composite material, so that a green, en
