Tailored polymer thin films enabled by initiated chemical vapor deposition (iCVD): From fundamentals to functional applications — •Stefan Schröder — Christian-Albrechts-Universität zu Kiel, Kiel, Germany

Functional polymer thin films are of great interest in vast application fields ranging from electronic devices to biomedical interfaces. Device miniaturization and the consequent need for new polymer films on the nanoscale demand precise thickness control and defect free films. Solvent-free initiated chemical vapor deposition (iCVD) meets these demands, because it circumvents de-wetting and surface tension effects encountered in conventional solution-based polymer thin film fabrication. The process provides conformal polymer coatings on the nanoscale on large-area substrates as well as complex geometries. In addition, it enables deposition on delicate substrates like flexible organic substrates, copy paper and biomedical patches at room temperature. This talk demonstrates the versatility of the iCVD process and highlights recent results from fundamental studies based on density functional theory (DFT) on the underlying reaction processes up to the application of iCVD films in sensors, biomedicine and electronic devices.
