Multifunctional films by tailoring chemistry and morphology of polymer brushes at the nanoscale — •Petra Uhlmann and Alexander S. Münch — Leibniz-Institut für Polymerforschung Dresden, Hohe Strasse 6, 01069 Dresden

Functional polymer thin films, like stimuli-responsive polymer brushes or cross-linked polymer networks, are a group of smart surface coatings which are beneficial for the design of intelligent interfaces. One emphasis of our work is the synthesis of polymer brushes as a toolbox for the creation of specific surface functions and stimuli-responsive layers using a bottom-up approach. For many technical applications control and switching of wettability is a key property. In this contribution it will be shown how tailored co-polymers containing zwitterionic phosphorylcholine groups (MPC) and benzophenone (BPO) as anchoring and UV cross-linking units can be used to create multifunctional films with easy-to-clean, anti-fog, anti-fouling and anti-icing properties. For the achievement of the desired surface functions the control of not only the wettability, but also other thin film properties like thickness and degree of swelling, are crucial and require the respective optimization of the chemical polymer composition and the degree of crosslinking. For verification and adjustment of the interfacial and thin film properties atomic force microscopy (AFM), infrared spectroscopy (ATR-FTIR), contact angle measurements, and in-situ spectroscopic ellipsometry were used and correlated with respective coatings performance and sustainability tests.
