  • Title: Green chemical functionalization of single-walled carbon nanotubes in ionic liquids.
    Author: Price BK, Hudson JL, Tour JM.
    Journal: J Am Chem Soc; 2005 Oct 26; 127(42):14867-70. PubMed ID: 16231941.
    Abstract:
    Single walled carbon nanotubes (SWNTs) are exfoliated and functionalized predominantly as individuals by grinding them for minutes at room temperature with aryldiazonium salts in the presence of ionic liquids (ILs) and K(2)CO(3). This constitutes an extremely rapid and mild green chemical functionalization process for obtaining the individualized nanotube structures. A number of ILs and various reaction conditions were surveyed. Raman, XPS, UV/vis/NIR spectroscopies, thermogravimetric analysis, and atomic force and transmission electron microscopies were used to characterize the products.
