Growth and microstructure of polymer- metal composites prepared by pulsed laser deposition — •Johanna Röder, Jörg Faupel, and Hans-Ulrich Krebs — Institut für Materialphysik, Universität Göttingen, Friedrich-Hund-Platz 1, 37077 Göttingen

Polymer-metal composites have a wide range of applications. Heading towards new materials with tailored properties, understanding of growth behaviour is one of the main goals. Using pulsed laser deposition it is possible to prepare such different material classes as polymers and metals in a one-step process. Samples were prepared in an UHV chamber at room temperature using a KrF excimer laser at 248 nm. The matrix for later cluster growth was Polymethylmethacrylate (PMMA) or Poly-bisphenol-A-carbonate (PC). The polymers were analysed by FTIR and X-ray reflectometry. The embedded metal clusters consist of Ag, Cu or a combination of Ag/Cu or Ag/Nb, and were mainly characterized using TEM. Different scenarios such as the growth of pure Ag or Cu on PC or PMMA, and furthermore the influence of Cu or Nb acting as a seed for later cluster growth will be presented and discussed.
