Gas-phase surface modification is a key technology for the processing and manufacture of many materials. Three experimental methods were used in this research to modify the surfaces: (1) Vacuum UV (VUV) photo-oxidation of single-walled carbon nanotubes (SWNTs) paper, polystyrene and Nafion®-117; (2) Microwave (MW) plasma discharge of an Ar-O2 mixture producing oxygen atoms in the absence of radiation to treat SWNT paper and polystyrene; and (3) UV bromination employing photolysis of gaseous HBr at different wavelengths (253.7 & 184.9 nm and 253.7 nm) to treat SWNT paper and powder. The quantitative and chemical changes in the top 2-5 nm of the samples' surface were analyzed using X-ray photoelectron spectroscopy (XPS).
