  • Publication number: 20120114549
    Abstract: A method for separating metal carbon nanotubes with a single graphene layer (m-SWNT) and semiconductor nanotubes with a single graphene layer (sc-SWNT) is provided. The method may comprise a step for grafting, notably by radical chemical grafting, a diazonium salt derivative on a mixture of m-SWNTs and sc-SWNTs so as to obtain a mixture of grafted m-SWNTs, and non-grafted sc-SWNTs, whereby the grafted m-SWNTs and the non-grafted sc-SWNTs separate because of differential chemical and/or physical properties caused by said grafting. In addition, a kit for separating m-SWNTs and sc-SWNTs is provided.
