High Performance Properties

Carbon nanotubes offer superior electrical conductivity (~10^6 S/m), exceptional tensile strength (up to 63 GPa), and outstanding thermal conductivity (up to 3500 W/m.K theoretically). With aspect ratios greater than 1000 and surface areas as high as 1315 m/g, CNTs provide an unmatched combination of strength, stability, and conductivity required for advanced applications.


Diverse Applications Across Industries

CNTs are integral to sectors ranging from electronics and aerospace to energy and medicine. They serve as conductive and structural additives in composites, enhance battery and supercapacitor performance, provide EMI shielding, and act as highly sensitive sensors. Their biomedical utility encompasses drug delivery and imaging, supported by their structural versatility and high purity.


Manufacturing Excellence and Quality

Produced using advanced methods such as chemical vapor deposition (CVD), arc discharge, and laser ablation, CNTs typically boast purities above 95%. Stringent manufacturing and quality controls help minimize trace metal catalyst residues (Fe, Ni, Co), ensuring reliable performance and suitability for diverse, high-tech applications.


Optimal Handling and Storage Guidelines

To preserve their properties, CNTs should be stored in cool, dry, and inert environments, avoiding exposure to moisture. Their non-porous, hydrophobic structure resists water absorption, while their high thermal and dimensional stability make them easy to handle, transport, and incorporate into a wide variety of systems and formulations.

FAQs of Carbon Nanotubes (Multi and Single Walled):


Q: How are single-walled and multi-walled carbon nanotubes manufactured?

A: Carbon nanotubes are produced using methods like chemical vapor deposition (CVD), arc discharge, and laser ablation. These processes yield either single-walled nanotubes (SWCNTs), featuring a single graphene cylinder, or multi-walled nanotubes (MWCNTs), which consist of multiple concentric graphene layers.

Q: What are the ideal storage conditions for carbon nanotubes?

A: Carbon nanotubes should be stored in a dry, cool, and inert atmosphere to prevent moisture uptake and oxidation. Proper storage ensures long-term stability and maintains the outstanding electrical, mechanical, and thermal properties of the CNTs.

Q: When are carbon nanotubes most beneficial in composites?

A: CNTs provide maximum benefit in composites when superior electrical conductivity, mechanical strength, or lightweight reinforcement are requiredsuch as in aerospace structures, automotive parts, and sports equipment. Their high aspect ratio and surface area promote strong matrix interactions, enhancing composite performance.

Q: Where are carbon nanotubes commonly used in India?

A: In India, carbon nanotubes are widely utilized by research institutions, manufacturers, electronics manufacturers, medical device companies, and material suppliers. Their applications span supercapacitors, lithium-ion batteries, EMI shielding materials, and advanced sensors, making them essential for technology and industry innovation.

Q: What is the process for incorporating CNTs into end-use products?

A: CNTs can be added as powders, dispersions, or aligned films/yarns, depending on the target application. They are mixed into matrices (such as polymers or metals) during composite fabrication, or deposited as thin films or coatings for use in electronics, sensors, and energy devices.

Q: How does the chemical composition affect CNT performance?

A: Composed of pure carbon (>90% with trace metal residues), CNTs possess highly ordered atomic structures which contribute to their exceptional electrical, thermal, and mechanical properties. High purity ensures consistent performance, which is critical for sensitive applications like medical devices and electronics.

Q: What are the primary benefits of using carbon nanotubes?

A: The main benefits of CNTs include tremendous strength-to-weight ratio, high electrical/thermal conductivity, large surface area, resistance to environmental degradation, and unique nanoscale morphology. These advantages support innovation across a broad spectrum of high-performance applications.
