Carbon nanotubes, particularly multi-walled variants, are extensively utilized in various advanced technological applications due to their exceptional mechanical, electrical, and thermal properties. In the field of electronics, they are employed to create highly conductive and flexible components, such as transistors, sensors, and interconnects, enhancing the performance and durability of electronic devices. Their high strength-to-weight ratio makes them ideal for reinforcing composite materials used in aerospace, automotive, and construction industries, resulting in lighter and more robust structures. Additionally, multi-walled carbon nanotubes are used in energy storage systems, including batteries and supercapacitors, where they improve charge capacity and longevity. In biomedical applications, they serve as carriers for drug delivery systems and as scaffolds for tissue engineering, leveraging their unique properties to enhance medical treatments and regenerative medicine. Their ability to efficiently conduct heat also makes them valuable in thermal management solutions for high-performance electronics and industrial equipment.

Furthermore, they are applied in environmental remediation, such as water purification, where they act as filters or adsorbents to remove contaminants due to their high surface area. In coatings, multi-walled carbon nanotubes enhance wear resistance and provide corrosion protection for various surfaces.
