Inverse Gas Chromatography (IGC) was used to characterize the surface properties of pristine single-walled nanotubes as well as those modified by acidic functionalization. The dispersive component of the surface free energy of adsorption was determined using alkane probes. For the specific component, different polar probes were used. In addition, enthalpies of adsorption of probe molecules and the acidic (Ka) and basic (Kb)parameters of the surfaces are reported.
