Interpreting of XPS C1s Binding Energies in Silicon Containing Polymers and Nanoparticles

Article Preview

Abstract:

A method for predicting XPS C1s binding energies in polymers has been developed previously [1]. The calculation uses partial atomic charges determined quantum chemically (by the semi-empirical AM1 Method), which are found to provide a linear correlation with the binding energies corrected by the so-called Madelung intramolecular potential. We used this method successfully for interpreting XPS spectra of partially degraded fluoropolymers [2]. In the current contribution we investigate the possibility of developing a similar equation to describe siliconcontaining polymers that are medically and technologically important, and also some nanoparticles based on organo-silicon compounds.
