Abstract
We have studied the properties of untreated and O2 (or N2) plasma treated polyphenylquinoxaline (PPQ) polymer surfaces by X-ray absorption near edge spectroscopy (XANES). Upon comparing, with our previous XPS results, the measurements performed at the C and N-K edges under normal or glancing incidences, it is clear that XANES provides new information on the electronic properties and on the preferential orientation of the spin coated polymer film. It is shown, in particular, that the plasma treatment strongly modifies the antibonding [MATH] and [MATH] resonances.
