Description
Multi Walled Carbon Nanotubes 20-30nm
Our Multi Walled Carbon Nanotubes 20-30nm are made by CCVD and purified using concentrated acid chemistry. Carbon Nanotubes (CNTs) have proven to offer a unique properties of stiffness and strength largely due to their high aspect ratio and all carbon structure. The thermal and electrical conductivity found in CNTs is much higher than that of other conductive or fibrous additive materials. Surfactants are used to stabilize dispersions in DI Water or other aqueous solvent mixtures. The most common surfactants used are PVP, SDS, or SDBS. The carbon atoms in CNTs are arranged in a planar honeycomb lattice structure in which each atom is connected via a strong chemical bond to the three neighboring atoms. These strong bonds are the reason that the basal plane elastic modulus of graphite is one of the largest of any known material. Having such strong bonds at the atomic level as well as a high aspect ratio, Carbon Nanotubes are expected to be the ultimate high-strength fibers.
