Vertical arrays of carbon nanotubes, called ‘forests’, are a common type of three-dimentional (3D) nanotube assembly. Vertical arrays effectively preserve and often accentuate the unique anisotropic properties of individual carbon nano tubes and posses a morphology that may be precisely controlled.These forests can be produced by chemical vapor deposition technique and used for diverse applications such as in highly elastic conductive composites, photo- or thermoacoustics, for mechanical nanomanipulation, in catalysis or as sensors in nanomedicine.

Alignment is an important parameter for characterizing CNT bulk assemblies in terms of the theoretical limits of electrical and thermal conductivities and mechanical strength for individual CNTs. The scattering patterns reveal continuously varying alignment order along the growth direction and two distinctly different morphologies of CNTs.
Dr. Huojin Chan (University of Science and Technology of China, Hefei, Anhui, China)
The aligned CNT arrays are good templates to grow other ordered nanostructures. Other materials can directly deposited on CNT surface by physical vapor deposition (PVD). Such PVD processes such as sputter deposition offer a relatively simple and clean route to synthesize other nanotubes.

Additionally the carbon nanotubes can act as the templates to confine the chemical reaction to grow nanorods. Bulk CNT are also widely applied in many cases to improve the mechanical, thermal, electrical, and other physical properties of the target materials. The CNTs are random or aligned in these composites. CNTs can also be aligned in the composites to form aligned-CNT composites.
Dr. Hans Roelofs Ph.D (National Technical University of Athens, Greece)
Carbon nanotube arrays are the most promising candidates as a kind of superstrong material for application in superstrong fibers, bullet-proof vests, aeronautics and extraneous materials, and even space elevators due to their extraordinary mechanical strength and high Young’s modulus. The self-assembly of carbon atoms into an ultralong CNT with a perfect structure is a rigid process during which the mass, heat and momentum transfers have reached their upper limits and are highly susceptible to the environmental conditions
This material ships as dry granules or powder. Each grade contains particles with an average thickness and surface area. All dimensions represent median sizes and there is a distribution around the mean. Aligned Nanotube Arrays by Nanoshel.
