Abstract

The invention discloses a method for plating a nickel layer on the surface of a multiwall carbon nanotube, and relates to a method for plating a metal layer on the surface of the multiwall carbon nanotube. The invention solves the problems that the multiwall carbon nanotube is subject to aggregation and reacts with oxide easily to cause structural damage. The method comprises the following steps: firstly, acidizing treatment; secondly, preparation of sensitizing solution; thirdly, sensitization treatment; fourthly, activation treatment; and fifthly, plating treatment. After the nickel layer is plated on the surface of the multiwall carbon nanotube by the method, the Van der Waals force of the surface of the multiwall carbon nanotube is weaken and the problems that the multiwall carbon nanotube has the trend of mutual intrication and is subject to aggregation easily can be improved; and the nickel layer on the surface of the multiwall carbon nanotube can protect the carbon nanotube and can prevent the surface of the multiwall carbon nanotube from being damaged by other media (oxidizing medium and corrosion medium). In addition, due to the fine size of carbon nanotube, nickel with the crystal grain on the nano-scale can be better dispersed and the chemical catalytic activity of the nickel can be improved.

Description

technical field

[0001] The invention relates to a method for plating a metal layer on the surface of a multi-walled carbon nanotube. Background technique

[0002] Carbon nanotubes are formed by curling graphite sheets. The sheets are composed of carbon-carbon bonds with the highest strength in nature, and the sheets are composed of van der Waals forces. Due to the van der Waals force, multi-walled carbon nanotubes are easy to agglomerate and difficult to disperse. Because there are no redundant dangling bonds on the surface of carbon nanotubes, they are in an inert state, making it difficult to interact with other chemical substances in many cases; and carbon nanotubes are easy to react with oxidizing substances and some metals, causing structural damage.
