Ni Coated Multi-walled Carbon Nanotubes (MWCNTs) are widely used in various advanced technological applications due to their unique properties. They are particularly valued in the field of energy storage, where they serve as efficient electrode materials in batteries and supercapacitors. The nickel coating enhances electrical conductivity and provides catalytic activity, making them suitable for use in fuel cells and hydrogen storage systems.

In the electronics industry, these nanotubes are utilized in the development of conductive films, sensors, and electromagnetic interference shielding materials. Their high surface area and mechanical strength also make them ideal for reinforcing composites, improving the durability and performance of materials used in aerospace, automotive, and construction sectors.

Additionally, Ni Coated MWCNTs are employed in catalysis, where they facilitate various chemical reactions, including hydrogenation and carbon nanotube synthesis. Their magnetic properties, imparted by the nickel coating, are leveraged in biomedical applications such as targeted drug delivery and magnetic resonance imaging (MRI) contrast agents. This versatility makes them a critical component in advancing modern technology and innovation.
