Microstructure and mechanical properties of pulsed laser deposited PMMA and PMMA-metal structures — •Thorsten Scharf, Johanna Röder, Erik Süske, Jörg Faupel, and Hans-Ulrich Krebs — Institut für Materialphysik, Universität Göttingen, Friedrich-Hund-Platz 1, D-37077 Göttingen

Thin films of composite materials are of high interest for a wide range of applications. Especially nano-composites consisting of different material classes, e.g. polymers and metals, are difficult to prepare. Here pulsed laser deposition (PLD) is an interesting preparation technique due to its flexibility. On this poster the growth mechanisms of different metals on laser deposited PMMA will be discussed with a focus on the possibility to modify the growth. By depositing metals of different reactivity acting as nucleation seeds it is possible to control the cluster size distribution and therefore for instance the optical properties. The mechanical properties, especially of the polymeric part of the films, are changed during deposition due to the PLD process. They can be measured by mechanical spectroscopy, which was performed using an new in-situ setup. Experimental details as well as results will be presented and discussed in this contribution.
