An international team of researchers, led by Distinguished Professor Rodney S. Ruoff (Department of Chemistry) from the Center for Multidimensional Carbon Materials (CMCM), within the Institute for Basic Science (IBS) at UNIST, has synthesized a film composed of densely packed diamond-like carbon nanofibers. As described in a recent article published in the journal ACS Nano, the researchers noted that the new carbon material has a high concentration of tetravalently-bonded carbons (the diamond-like nanofibers have many C atoms with four other atoms bonded to them; this is also referred to as "sp3-bonded carbon").
"The diamond-like carbon nanofiber films were synthesized by heating copper nanoparticles of few nanometers in diameter on a substrate, in acetylene and hydrogen gasses," says Kee Han Lee. "The synthesized fibers were highly dense and formed a film. These densely packed nanofibers could also be separated into a powder form which could potentially broaden their applications."
