Advanced surface chemical analysis of plasma modified polymers and plasma-polymers
- A comprehensive characterization of plasma modified polymer surfaces or plasma-polymerized thin films needs access to parameters as - concentration of saturated/unsaturated carbon species (e.g. aromaticity) or other double bonds as C=N or C=O, - branching, and - losses of crystallinty or other degrees of structural order. Furthermore the complex ageing phenomena of plasma modified polymers/plasma-polymers and the measurement of an in-depth distribution of chemical species are challenges for the analyst. The talk will display selected examples where such challenges have been met by using advanced methods of surface chemical analyses as Photoelectron Spectroscopy with variable excitation energy (“SyncXPS”), X-ray Absorption Spectroscopy (NEXAFS) at C, N and O K-edges and Time-of-Flight Secondary Mass Spectroscopy (ToF-SIMS) combined with Principal Component analysis (PCA).
