The efficiency of miniaturization crucially relies on the ability to tailor complex systems on the nanoscale. We used swift heavy ion irradiation as a tool to yield highly controllable nanometer sized features. Hence, we studied the structure and morphology of irradiated Polydimethylsiloxane (PDMS) thin films by means of small angle x-ray scattering (SAXS) and infrared spectroscopy. We found first evidence of ion tracks in silicon based polymers. Furthermore, in situ stretching experiments using SAXS show the appearance of cyclic elastically deformable ion tracks in PDMS. This offers adjustable nanostructures for new applications.
