Abstract
The screening ability of water dipoles inside finite-length armchair single-walled carbon nanotubes (SWNT) within a self-consistent π-orbital tight binding (TB) method, was investigated. A parallel dipole was induced when an external dipole was positioned outside the entrance of nanotube, which may favor the entering of external dipole molecules. This method was applied to study the polarization of a short SWNT segment filled with a 6-water-wire, with geometry obtained from classic molecular dynamics (MD) simulations. The results show that the induced charges on the SWNT surface effectively reduce the total water dipole of 12.23 Debye to a net dipole of 5.24 Debye.
