Formation of Metal/Polymer Interfaces by Metal Evaporation: Influence of Deposition Parameters and Defects — •Vladimir Zaporojtchenko, Knut Behnke, Thomas Strunskus, and Franz Faupel — Lehrstuhl für Materialverbunde, Technische Fakultät der CAU Kiel, Kaiserstr. 2, 24143 Kiel

The growth of a metal layer on a polymer surface is determined by

the basic processes occurring in the initial stages of

metal/polymer interface formation. The interplay between

adsorption, nucleation, diffusion and cluster growth can be used

to obtain different morphologies in a controlled manner simply by

a variation of the preparation conditions. Metal/polymer

interfaces with different but well defined morphologies were

prepared by evaporating noble metals (Au, Ag, Cu) onto chemically

different polymers, i.e., bisphenol-trimethyl cyclohexane

polycarbonate (TMC-PC), pyromellitic dianhydride-oxydianiline

(PMDA-ODA) polyimide (PI), polystyrol (PS) and Teflon AF 1601. On

some of the polymers the influence of defects, created by ion

bombardment, was investigated. The evolving interfaces were

characterised using transmission electron microscopy (TEM),

x-ray photoelectron spectroscopy (XPS) and atomic force

microscopy (AFM).
