Carbon Nanotubes Description
Carbon nanotubes (CNT) are tubes composed of carbon with diameters typically measured in nanometres. CNTs are cylindrical molecules that consist of one‐atom‐thick sheets of carbon (graphene) rolled into a tube.
Stanford Advanced Materials (SAM) supplies single‐walled (SW) and multi‐walled (MW) carbon nanotubes with a purity of > 95 wt.-%. They are functionalised with -OH or -COOH groups.
Length: 5-25 µm
Ash content: <2.0 wt.-%
Properties:
- Tensile strength: CNTs have been measured with tensile strengths ranging between 30 GPa and 150 GPa.
- Electrical conductivity: CNTs exhibit electrical conductivities of up to 1×10^6 S/m, making them suitable for use in microelectronics, sensors and transparent conductive films.
- Thermal conductivity: CNTs possess thermal conductivities that can exceed 3 000 W/(m·K). This property supports their use in heat sinks, thermal interface materials and cooling solutions.
- Low density: CNTs have a density of approximately 1.3–1.4 g/cm³. This low mass is advantageous in sectors where weight reduction is essential, such as aerospace and the automotive industry.
Versatility: CNTs can be functionalised to adjust their surface characteristics and to achieve improved compatibility with various materials for specific applications.
