Description
Multi-Walled Carbon Nanotubes (MWCNTs)
Purity: >95% | Outer Diameter: 10–20 nm | Length: 10–30 µm
Multi-Walled Carbon Nanotubes (MWCNTs) are cylindrical nanostructures composed of multiple concentric graphene layers. Known for their exceptional electrical conductivity, mechanical strength, and thermal stability, MWCNTs are among the most versatile and high-performance nanomaterials available today. With an outer diameter ranging from 10 to 20 nm and a high specific surface area of 220 m²/g, they are engineered for maximum efficiency in numerous high-tech applications.
Manufactured using Chemical Vapor Deposition (CVD), these carbon nanotubes offer consistent quality, structural uniformity, and scalable performance—making them ideal for industries ranging from energy storage and nanoelectronics to biomedicine and advanced composite engineering.
