Abstract

The invention discloses a method for preparing a CNTs/Ni composite material through composite electrodeposition, and relates to a method for preparing a composite material through composite electrodeposition, for solving the problem of low dispersibility of carbon nano-tubes in a composite material prepared by the prior art. The method comprises the following steps: 1. mixed acid treatment; 2. pH value adjustment; 3-4. vacuum filtration; and 5. composite electrodeposition. According to the method disclosed by the invention, the composite material with nano-tubes which are uniform in dispersion, free from interface reaction and high in interface bonding strength in a metal matrix can be obtained by means of composite electrodeposition. The method disclosed by the invention is used for preparing the CNTs/Ni composite material.

Description

technical field [0001] The invention relates to a method for preparing composite materials by composite electrodeposition. Background technique [0002] Carbon nanotubes have excellent mechanical properties, electrical properties, magnetic properties, optical properties, and thermal properties. In some special fields (such as space exploration), high-performance, lightweight, and high-strength structural materials are required. Carbon nanotube-reinforced metal composite materials Has application potential. Therefore, carbon nanotubes are considered to be an ideal reinforcement for composite materials. However, the dispersion of carbon nanotubes in the metal matrix, the interface reaction with the metal matrix and the state of interface bonding directly affect the performance of the composite material. Due to the large specific surface area of ​​carbon nanotubes, they are easily entangled and agglomerated under the action of van der Waals force. Once the dispersed carbon na...
