STUDY OF ULTRATHIN POLYAMIDE-6,6 FILMS ON CLEAN COPPER AND PLATINUM

The aim of this work is to present an interaction reactor which allows us to build very thin organic coatings on metallic substrates. This r eactor is coupled to an analytic device which further enables an inves tigation of the interfacial region by very-surface-sensitive analytica l means. The use of such an integrated installation makes it possible to follow the growth of the interfacial region step by step and to foc us on the nature of the chemical structure that is identified in the i nterfacial region between a well-defined polymer phase and an atomical ly clean metallic substrate. As an illustration we compare the behavio r of PA-6,6 on copper and platinum. (C) 1997 American Vacuum Society.
