Product Description:
TimestubTM ---Graphitized Multi-walled Carbon nanotubes---have three kinds of products: TNGM5, TNGMH5 and TNGMC5. TNGMH5 and TNGMC5 are TNGM5 hydroxyl and carboxyl functionalized products, respectively.
Graphitized multi-walled carbon nanotubes are purified under inert gas for about 20hours at 2800°C thermal treatment.The graphitized multi-walled carbon nanotubes have the highest graphite crystallization, the best electrical conductivity and the best inoxidizability. The electrical conductivity can be compared with graphite powder, and the ignition temperature can reach 800°C.
