We calculate the interaction energy and force between atoms and molecules and single-walled carbon nanotubes described by the Dirac model of graphene. For this purpose the Lifshitz-type formulas adapted for the case of cylindrical geometry with the help of the proximity force approximation are used. The results obtained are compared with those derived from the hydrodymanic model of graphene. Numerical computations are performed for hydrogen atoms and molecules. It is shown that the Dirac model leads to larger values of the van der Waals force than the hydrodynamic model. For a hydrogen molecule the interaction energy and force computed using both models are larger than for a hydrogen atom.

In our research, we aim to formulate SWNTs ink and develop a methodology to create enhanced conductive flexible transparent SWNTs films that have the potential to possibly reduce the use of ITO. In our preliminary findings, we achieved a sheet resistance of 25.1 kΩ/sq with ∼93% transparency (excluding film) by spraying a unsorted purified pristine SWNTs. In-house separated M-SWNTs, prepared using agarose gel separation methods, were sprayed with sheet resistance of 3.3 kΩ/sq and ∼86% transparent.. Investigation of tube length with respect to conductivity was also studied — nanotubes were sonicated for different durations (thus affecting tube length) before separation and spraying.
