Applications of Few Walled Carbon Nanotubes (FWNTs)

To date, carbon nanotubes (CNTs) are strongest single molecules measured and are believed to increase the performance of structural composites. However, SWNTs and MWNTs have provided only limited enhancements to the mechanical properties of polymer matrix and the composite processing is still limited to bench-top scale. FWNTs-defined as nanotubes with sidewalls of 2 to 5 layers, diameters ranging from 3 to 8 nm and lengths around tens of micrometers are unique small diameter MWNTs with near perfect graphitization structure. (See right figure) We have investigated the enhancement of mechanical properties in FWNTs-polymer composites. (See left figure). It is observed that the Young's modulus of composite films with only 0.2wt % functionalized FWNTs shows a remarkable reinforcement value of dY/dVf = 1658 GPa, which is 200% higher than the highest value (dY/dVf = 800 GPa) that was previously reported. We believe that FWNTs are the optimum reinforcing filler for the next generation of composite materials.
