Description
Single Walled-Double Walled Carbon Nanotubes 99
Our Single Walled-Double Walled Carbon Nanotubes 99 are made by CCVD and purified and functionalized 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. This product is produced by CCVD and is further purified or functionalized using a Dielectric Barrier Discharge process which provides greater control over the desired type & amount of functionality which produces an exfoliated product that is much easier to disperse in the host matrix.
