Embodiment 1

[0020] Wash the carbon fiber with dimethylformamide for 20 h until the surface impurities are completely removed. Prepare 2g / L AgNO 3 Place in a sealable container while adding ethanol. Then put the carbon fiber into the solution to ensure that it is completely submerged in the solution. After argon gas aeration for 10 minutes, the container is quickly sealed, and the airtight container filled with the solution is γ-irradiated at room temperature. The irradiation dose is 30KGy. The rate was 30Gy / min; after the irradiation reaction was completed, the carbon fiber was taken out and dried to obtain a carbon fiber with a silver metal layer on the surface.

Embodiment 2

[0022] The carbon fiber was washed with tetrahydrofuran under reflux for 30 h until the surface impurities were completely removed. Prepare 4g / L Ni(NO 3 ) 2 ·6H 2 O in a sealable container while adding isopropanol. Then put the carbon fiber into the solution to ensure that it is completely submerged in the solution. After nitrogen aeration for 20 minutes, the container is quickly sealed, and the airtight container filled with the solution is subjected to γ-irradiation treatment at room temperature. The irradiation dose is 60KGy, and the dose rate 60Gy / min; after the irradiation reaction is completed, the carbon fiber is taken out and dried to obtain a carbon fiber with a nickel metal layer on the surface.

Embodiment 3

[0024] The carbon fibers were reflux washed with acetone for 48 h until the surface impurities were completely removed. Prepare 8g / L of Cu(NO 3 ) 2 Place in a sealable container while adding tert-butanol. Then put the carbon fiber into the solution to ensure that it is completely submerged in the solution. After being aerated with helium for 30 minutes, the container is quickly sealed, and the airtight container filled with the solution is subjected to γ-irradiation treatment at room temperature. The irradiation dose is 100KGy. The rate was 100Gy / min; after the irradiation reaction was completed, the carbon fiber was taken out and dried to obtain a carbon fiber with a copper metal layer on the surface.

Abstract

The invention discloses a method for depositing metal on carbon fiber surfaces. The method comprises the steps that a metal salt and free-radical scavenger mixed solution is taken as an irradiation medium, metal ions are reduced into elemental metal under the efficient metal ion reducing action of gamma-rays and the elemental metal is deposited on the carbon fiber surfaces, so that the interfacial compatibility of carbon fibers and a metallic matrix is improved. The method has the advantages as follows: (1) gamma-irradiation has high energy efficiency and strong penetrating power, and reduction of the preparation cost is facilitated; (2) an irradiation process is simpler and easier to control, and little environmental pollution is produced; (3) the method is suitable for batch preparation, and industrialized production for metallization of the carbon fiber surfaces can be realized.

Description

technical field [0001] The invention belongs to the technical field of material modification, in particular to a method for depositing metal on the surface of carbon fibers. Background technique [0002] Carbon fiber is a new type of fiber material formed by stacking flake graphite microcrystals along the axial direction. It has many excellent properties, such as good electrical conductivity, high strength, high modulus, corrosion resistance, and high temperature resistance. Due to these excellent properties, carbon fibers are often used in electromagnetic shielding materials, antistatic materials, battery electrodes, etc., and thus have a wide range of applications in electronic communications, oil exploration, infrastructure and other fields. At the same time, carbon fiber can also be added to metal and alloy materials as a reinforcing material to form a metal matrix composite material, thereby improving its high temperature resistance, corrosion resistance, fatigue resist...
