The adsorption of methanol and ethanol onto room temperature single-walled carbon nanotubes has been investigated using FTIR spectroscopy and computational simulations. FTIR data suggest that methanol does not remain adsorbed at room temperature. Conversely, ethanol does adsorb at room temperature. The FTIR data suggest that the ethanol molecules are extensively hydrogen-bonded, just as they are in the liquid phase. Comparison to the literature and computational simulations indicate that the ethanol molecules likely form adsorbed clusters on the nanotube bundles. The lack of evidence for a strong attractive force between the nanotubes and the ethanol has implications for the electrical properties of nanotubes, which will be discussed.
