Abstract

The invention relates to a preparation method of a carbon nano tube metal composition, comprising the following steps: providing a water solution containing metal ions and a water-soluble polymer containing carbonyl or hydroxyl; dissolving the water-soluble polymer into water; adding the water solution containing the metal ions to the water solution of the water-soluble polymer to form a first mixed solution; adding the water solution of a carbon nano tube into the first mixed solution to obtain a second mixed solution; and adopting the light the wave length of which is less than 430nm to irradiate the second mixed solution to form the carbon nano tube metal composition.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, in particular to a carbon nanotube metal composite and a preparation method thereof. Background technique [0002] Carbon nanotubes have been widely used in high-tech fields such as new composite materials and nanoelectronic devices because of their excellent electrical conductivity, thermal conductivity, and mechanical properties. The composite of carbon nanotubes and metal materials can further improve the conductivity, chemical properties, lubricity and hardness of carbon nanotubes. The composite can not only be used as an excellent conductive material, but also as a corrosion-resistant and wear-resistant Coatings, thermal barrier and sealing coatings and microwave absorbing materials. [0003] In recent years, the composite of carbon nanotubes and metal particles has become a research hotspot. Due to the large specific surface area and high electrical conductivity of ...
