摘要：

Near edge X-ray absorption fine structure (NEXAFS) microscopy has evolved into a powerful characterization tool for polymeric materials. The foundation of this utility depends crucially on the sensitivity of NEXAFS to the specific chemical structure of the polymer. Furthermore, for quantitative compositional analysis, reliable reference spectra with known energy resolution and calibrated energy scale are required. We report a set, of NEXAFS spectra from 24 common polymers that represent a range of chemical functionalities in order to create a database of calibrated polymer NEXAFS spectra to be used for compositional analysis. These spectra illustrate the sensitivity of NEXAFS spectroscopy to the polymer composition, illustrating the potential of NEXAFS for chemical analysis. (C) 2002 Elsevier Science B.V.
