Nanotubes and Fullerenes

Sigma-Aldrich offers a wide selection of carbon nanomaterials, including carbon nanotubes (CNTs) and fullerenes (buckyballs). Available CNTs are classified into multi-wall nanotubes (MWCNTs), double-wall nanotubes (DWCNTs), and single-wall nanotubes (SWCNTs). In addition, SWCNTs are available with chemical functions covalently grafted to the nanotube outer surface. Fullerenes are available in several degrees of purity and with a wide variety of chemical functions. The functionalized fullerenes include a library of all PCBM derivatives shown to be important for research in Display and Optoelectronics.
