Аннотация
This work reports a theoretical study of nicotine molecules interacting
with single wall carbon nanotubes (SWCNTs) through ab initio
calculations within the framework of density functional theory (DFT).
Different adsorption sites for nicotine on the surface of pristine and
defective (8,0) SWCNTs were analyzed and the total energy curves, as a
function of molecular position relative to the SWCNT surface, were
evaluated. The nicotine adsorption process is found to be energetically
favorable and the molecule-nanotube interaction is intermediated by the
tri-coordinated nitrogen atom from the nicotine. It is also predicted
the possibility of a chemical bonding between nicotine and SWCNT through
the di-coordinated nitrogen. (C) 2010 Elsevier B.V. All rights reserved.
