(Phys.org) —Single-walled carbon nanotubes (SWCNTs) are being widely studied for their potential applications in many areas; for example, as electrode materials for energy storage, as transparent conductive films, and as nanocomposite materials with novel properties. But all of these applications require that the SWCNTs have a very high purity, since metallic impurities have adverse effects on the nanotubes' properties. So far, preparing SWCNTs with very few metallic impurities has been challenging.
