Abstract:

Single-walled carbon nanotubes SWNTs are widely recognized as being broadly applicable to advanced materials and systems important to the Air Force. However, the nanotube production generally yields mixtures, which presents major barriers in harvesting metallic-SWNTs as the minor fraction up to only 13 and also in obtaining highly pure semi-SWNTs electronic applications, for example. Their post-production separation in sufficient quantities has proven to be very challenging. Our project is to build upon our previous discovery to achieve efficient and quantitative separation into metallic and semiconducting fractions and, as related, to have a fundamental understanding of the underlying selective and specific molecular interactions responsible for the separation. In this project we made significant progress in improving the separation reagents and process, and the characterization and evaluations including those at the device level of the separated nanotube samples. The results are published or submitted for publication.
