Manufacturing Carbon Nanotubes

Abstract:
Carbon nanotube sheets, yarns, and their derivative products are beginning to emerge in the marketplace. The most productive and scalable manufacturing method in play today utilizes a chemical vapor deposition process for making very large format CNT non-woven textile-like sheets directly from the reactor without post processing. These materials are different from similar appearing "Bucky" papers in that they contain non-dispersible, long CNTs. Raw sheet strength is high (200MPa to 1GPa), and electrical conductivity (>2 x 106 S/m) is sufficient for superb EMI shielding and, even for replacing copper wiring for some applications. It is also possible to impregnate CNT rolls on commercial equipment with a wide variety of commercial resins including Bismaleimide toughened epoxy (BMI) and the cyanate ester family. An example of a roll of these sheets is shown in Figure 1. Yarns have been plied on commercial wire braiding machines to produce CNT wires ranging from 33 gauge to 22 gauge or lower.
