Abstract

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, environment-friendly, simple and efficient method is provided for modification and application of the carbon fiber.

Description

technical field [0001] The invention belongs to the field of surface and interface modification of materials, and in particular relates to a preparation method of nickel hydroxide / polyetheramine modified carbon fiber. Background technique [0002] With the improvement of carbon fiber composite material production technology and the continuous expansion of application fields, the demand for carbon fiber composite materials is increasing year by year. At the same time, the comprehensive performance requirements for carbon fiber composite materials have also been increasing. Carbon fiber has excellent mechanical properties such as high specific modulus and high specific strength. However, its surface lacks active groups and has low surface energy, which makes the interface bond strength between it and the resin matrix very poor, which greatly limits the high performance of carbon fiber. Therefore, in order to make composite materials with excellent mechanical properties, it is ...
