For researchers and scientists pushing the boundaries of material science, understanding the nuanced specifications of carbon nanotubes (CNTs) is fundamental to successful R&D outcomes. The performance of CNTs in any given application is intimately tied to their physical and chemical characteristics. As a leading manufacturer and supplier, we emphasize the importance of detailed specification knowledge when you buy carbon nanotubes, ensuring that your research projects are built on a solid foundation.

The most commonly cited specifications for CNTs include purity, average diameter, length, and BET (Brunauer–Emmett–Teller) surface area. Purity is critical; even small percentages of residual catalyst or amorphous carbon can significantly alter electrical, thermal, and mechanical properties. For applications requiring high conductivity or precise electronic behavior, sourcing CNTs with purity levels exceeding 95% is often necessary. We ensure our manufacturing processes yield CNTs that meet these demanding purity standards.

Average diameter is another key parameter. Single-walled carbon nanotubes (SWCNTs) typically range from 0.7 to 2 nm in diameter, while multi-walled carbon nanotubes (MWCNTs) can range from 2 nm up to 50 nm or more. The diameter influences the aspect ratio and the density of states, impacting electrical conductivity and mechanical strength. Length, similarly, plays a crucial role in forming conductive networks and reinforcing polymer matrices. Longer CNTs generally provide better mechanical reinforcement and conductivity.

The BET surface area, measured in m²/g, provides an indication of the total surface available for interaction. A higher BET surface area is often desirable for applications involving adsorption, catalysis, or as an electrode material in energy storage devices like supercapacitors. Our CNTs are characterized with high BET values, providing ample surface for your R&D experiments. When you are looking to buy carbon nanotubes for specific research, we can help you match the specifications to your experimental design.
