The plating solution of the present invention is only composed of copper salt, grain refiner and complexing agent, and the formula is simple; the electroplating solution of the specific composition and proportion of the present invention can make the nano-copper particles very uniformly coated on the carbon The surface of the nanotube, and the particle size of the nano copper particles coated on the surface of the carbon nanotube is 34-38nm.

Description

technical field [0001] The invention relates to an electroplating copper solution, in particular to a plating solution for electroplating copper on carbon nanotubes. Background technique [0002] Metal aluminum is often used as a heat sink due to its light weight, stable chemical properties, strong plasticity and good thermal conductivity. However, with the development of social science and technology, people have higher and higher requirements for heat sinks, and conventional metal materials are difficult to meet. its requirements. Carbon nanotubes are widely used in composite materials due to their ultra-high thermal conductivity (2000W / (m·K)), and their addition to composite materials can significantly improve the thermal conductivity of the material. However, as an inert material, carbon nanotubes have poor wettability with the base metal. Existing studies have shown that the wettability between them can be effectively improved by plating nickel or copper on carbon nano...
