Innovation; imagination becomes reality


explainWhat is a carbon nanotube?

What is a carbon nanotube?
It is a nanomaterial made of graphene in a tube shape,
single-layered carbon nanotubes are called single-walled carbon nanotubes (SWCNT),
Multi-layered are called multi-walled carbon nanotubes (MWCNT).
Because CNT’s length is microscale while its diameter is 0.6nm to several tens of nm, it is
also known as one-dimensional nanomaterials.
Physical properties (mechanical functions, conductivity, heat resilience) are beyond imagination.


propertiesExcellent features of a CNT.

For example, the mechanical properties of CNT are
Compared to steel, it has 100 times the tensile strength, 5 times the Young's modulus, and 1/6 the density.
These properties are stronger than even carbon fiber fabrics, which are made from the same carbon atoms.
Furthermore, it has 10 times the thermal conductivity and 1,000 times the electrical-current permissibility of copper,
Excellent flexibility, heat resistance, slidability and corrosion resistance.
