CR PHTHALIMIDE SYSTEM - XPS STUDY OF INTERFACIAL REACTIONS/

The Cr deposition on phthalimide has been investigated as a model syst em, for the understanding of interfacial interactions of Cr with polyi mides. The XPS measurements performed on such a simple system provide C(1s), O(1s) and N(1s) core level spectra, which could be interpreted without ambiguity. Thus, the analysis of all spectra indicates that, a t the initial stage of the formation of the Cr-phthalimide interface, the metal attack is mainly directed on the C=O function, and that at t his stage of the metallization, the phenylene ring is not involved in the interfacial interactions.
