Adsorption of metal atoms on polymers — •Vladimir Zaporojtchenko, Jörn Erichsen, Jurgita Zekonyte, Axel Thran, Pay Schulze Horn, and Franz Faupel — Technische Fakultät, Lehrstuhl für Materialverbunde, University of Kiel, Kiel, Germany

In this report, we present surface sensitive methods to determine the metal atom adsorption probability, which is described through the condensation coefficients of metals on polymers. Studying the condensation coefficient is useful to estimate the influence of different surface treatment on the adhesion of metals on polymers, or to study the chemical interaction between metal atoms and polymers. A large variation of the condensation coefficient of noble metals C is observed for different polymers. C ranges from close to unity to values of the order of 10−3, depending on the type of polymer and the metal. The condensation coefficient at room temperature is dominated by the most favorable interaction between the metal atoms and the polymer functional groups. The correlation between the morphological properties of the metal at an early stage of the deposition and C will be discussed.
