Embedding of Metal Clusters into Polymers: Calculations from XPS-Data — •Kai Dolgner, Jörn Erichsen, Vladimir Zaporojtchenko und Franz Faupel — Lehrstuhl für Materialverbunde, Technische Fakultät der Universität Kiel, Kaiserstr. 2, 24143 Kiel, Germany

Recently, there is much interest in nano-sized metal clusters, which form in the initial stage of polymer metallization if the metal in not too reactive. This interest does not only arise from quantum size effects and single-electron tunneling phenomena but is also triggered by applications in medicine and as substrates for biomolecules. The embedding of metal clusters in polymers by heating above the glass transition temperature is well known but the initial stage is not fully understood. We will present a method to derive informations about the embedding process from X-ray photoelectron spectroscopy (XPS) data for gold and copper on polystyrene and bisphenol-(A)-polycarbonate by means of a computer simulation.
