There are several methods of synthesis of carbon nanotube, like as CVD, arc discharge, laser ablation and etc., and CVD is used for our carbon nanotube. Because CVD is the most promising method for mass-production and enables CNTs’ growth with most controllability, such as length, alignment, density, etc.

Carbon Nanotube/Polymer Composites
CNTs have extraordinary mechanical and electrical properties. As additives, they can be used to reinforce the mechanical properties of matrix polymers to form high-performance nanocomposites for applications such as yacht masts, golf club shaft, bike accessories, etc. At the same time, carbon nanotube have shown great potentials in ESD (electrostatic discharge) material applications.
CNT Suspensions in Various Solvents
Besides NMP-based CNT suspensions, a variety of solvents will be available to disperse CNTs in order to be used in different nanocomposites as described above.
Metallic/Semiconducting CNT-based Transparent Conductive Membranes (Buckypapers)
With our successful CNT dispersion and separation techniques, buckypapers, based on different kind of CNTs, can be made. The potential applications include transparent conductive films to replace ITO in touch screens, etc.
