The scattering of gas molecules on quartz surfaces covered with the films of vertically aligned single-walled carbon nanotubes (VA-SWNTs) was investigated by the molecular beam technique. The high porosity of VA-SWNT films allows gas molecules to penetrate into the films and to have number of collisions with SWNT bundles before leaving the films. For this reason, the surface modification efficiently enhances the energy accommodation of incident molecules in spite of poor accommodation during each scattering event on SWNT. The measurements for the free-standing samples revealed that most molecules have enough number of collisions with SWNTs for efficient energy transfer within the randomly oriented layer at the topmost of the film.
