The behavior of dual thermo-responsive diblock copolymer (DBC) thin films in changing environmental conditions is investigated. The DBCs consist of a zwitterionic poly(sulfobetaine) (PSB) and a nonionic poly(acrylamide) (PAM) block. Systematically studies are performed that investigate, how external stimuli, including temperature, the composition of the surrounding vapor, and the salt content within the films, affect the thin-film behavior, using mainly neutron scattering techniques and infrared spectroscopy.

Translated abstract:
Das Verhalten von dual thermo-responsiven dünnen Diblock Copolymerfilmen (DBC) wird in wechselnden Umgebungsbedingungen untersucht. Die DBC bestehen aus einem zwitter-ionischem Poly(sulfobetain) und einem nicht-ionischem Poly(akrylamid) Block. In systematischen Studien wird der Effekt der Temperatur, der Zusammensetzung der Umgebungsatmosphäre, und des Salzgehalts, auf das Filmverhalten erforscht. Dazu werden hauptsächlich Neutronenstreumethoden und Infrarotspektroskopie verwendet.
