Because of its unique structure, carbon nanotubes have excellent electrical, mechanical, optical, and thermal properties, and have broad application prospects in high-performance materials, electronic devices, sensors, and molecular devices. However, the surface defects of carbon nanotubes and their poor compatibility with other materials limit their application. Therefore, expanding the application of carbon nanotubes through surface modification has gradually become a research hot spot. Carbon nanotubes can do some surface treatment, Ni plated multi-walled carbon nanotubes (referred to as MWCNTs-Ni) refers to the purification, sensitization and activation pretreatment of the original MWCNTs, and then using a method of electroless nickel plating to deposit a layer of metallic nickel on the surface and The prepared functionalized multi-wall carbon nanotubes. Compared with the original MWCNTs, MWCNTs-Ni has been improved in terms of dispersibility, corrosion resistance, electromagnetic properties and microwave absorption properties, thereby greatly broadening the application of MWCNTs in various fields.

Nickel-plated carbon nanotubes are widely used in anti-shielding.
