The structure of Multi Walled Carbon Nanotubes is unique, they come in a complex array of forms and because each concentric nanotube can have different structures, there are a variety of sequential arrangements. The simplest sequence is when concentric layers are identical but different in diameter. However, mixed variants are possible, consisting of two or more types of concentric Carbon Nanotubes (CNTs) arranged in different orders. These can have either regular layering or random layering. The structure of the carbon nanotubes influences its properties including electrical and thermal conductivity, density, and lattice structure. Both type and diameter are important. The wider the diameter of the carbon nanotube (CNTs), the more it behaves like graphite. The narrower the diameter of the Carbon Nanotubes (CNTs), the more its intrinsic properties depends upon its specific type.
Multi Walled Carbon Nanotubes Properties
Multi Walled Carbon Nanotubes properties come from their all carbon structure, extremely small geometries and high aspect ratio. MWNTs are a great choice of nanoscale additives and can improve mechanical properties as well as electrical and thermal conductivity in the products you add them into. They are typically added in 2-5wt% loading ratios. Masterbatches have 10, 15, or 20% Multi walled carbon nanotubes loading.

Russian Doll Multi Walled Carbon Nanotubes
Below is a representation of the atomic structure of russian doll MWNTs. Each concentric multi walled carbon nanotube can have different structures, and hence there are a variety of sequential arrangements. The simplest sequence is when concentric layers are identical but different in diameter. However, mixed variants are possible, consisting of two or more types of concentric Carbon Nanotubes (CNTs) arranged in different orders. These can have either regular layering or random layering.
