  • CARBON NANOSTRUCTURE COMPOSITIONS AND METHODS FOR PURIFICATION THEREOF
    Publication number: 20230227314
    Abstract: The present invention relates to carbon nanostructure compositions such as single walled carbon nanotubes (SWCNT), and methods for purification thereof, such as separation by their electronic types (e.g., primarily semiconductor enrichment). The type separated, semiconducting SWCNTs, can be used in many downstream applications such as printed electronics, sensors, optoelectronics and solar energy conversion, among other applications.
