Research on and with Scanning Force Microscopy

Properties of Polymer Surfaces

The morphology, topography, local stiffness, adhesion friction and optical properties of polymer surfaces made from a single component or consisting of a mixture of components with distinctly different properties are investigated at a wide range of temperatures. We develop novel measurement methods to realize a mechanical-dynamical characterization of polymer probes at the nanometer and kHz to MHz range. We combine our scanning probe microscopes with the variation of external parameters such as temperature, solvent and electrochemistry.

We currently investigate, among other systems, novel polypropene samples.

Additionally we use Scanning Nearfield Optical Microscopy, Raman/Brillouin Spectroscopy  and x-ray for characterization.

We are working on the synthesis of novel silane derived molecules to improve -contact printing. These molecules also help to functionalize AFM tips. We have collaborations with polymer producing companies. For inquiries please mail to Othmar Marti.

Forces in AFM

In the framework of a DFG sponsored network on Nanoelectrochemistry we investigate forces and potentials between sample surfaces and AFM tips. The goal is to understand image artefacts due to forces. the final report on this project can be found here.

Instrument Development

We have and do transfer our advanced instruments to the marketplace via our collaboration with Witec GmbH.
