Due to its high aspect ratio (within tens of nanometers in diameter, several microns to hundreds of microns in length), carbon nanotubes are the finest fiber materials at present, which have shown excellent mechanical properties and unique electrical properties. It is exciting that because it is a one-dimensional material with hollow structure, it can be used as a template to prepare a new kind of one-dimensional material.

Research shows that the average young's modulus of a single multi-layer carbon nanotube is 1.8tpa, showing super mechanical properties; the bending strength is 14.2gpa, showing super toughness. Therefore, carbon nanotubes will have a great prospect in the field of composite materials. However, nickel plating on its surface Nickle plate Multi Walled Carbon Nanobuts Ni-MWCNT will further improve the physical properties such as conductivity, corrosion resistance, hardness and lubricity. It can not only be used as an improved conductive material, but also as a corrosion-resistant, wear-resistant coating, thermal barrier and sealing coating, microwave absorbing material, etc. In addition, coating metal material on the surface of carbon nanotubes will form a continuous high-strength bond between carbon nanotubes and metal matrix, overcoming the poor bond between carbon nanotubes and metal matrix. This is an indispensable key step in the preparation of super composite materials by carbon nanotubes.
