The fouling resistance of zwitterionic coatings is conventionally explained by the strong hydrophilicity of such polymers. Here, the in vitro biocompatibility of a set of systematically varied amphiphilic, zwitterionic copolymers is investigated. Pho

Abstract The resistance of zwitterionic polymer coatings against the adsorption of proteins and the attachment of pathogenic bacteria is influenced by the precise molecular architecture of the polymers. Two until now rarely studied molecular variable

Supramolecular complexation is an attractive strategy to modulate the performance of surfactants, e.g., by host-guest interactions. Here, we investigate the interaction of single-chained, di-, tri-, and tetrameric cationic surfactants with cyclodextr

Oil-in-water (O/W) microemulsions typically feature a low viscosity and exhibit the ordinary viscosity reduction as a function of temperature. However, for certain applications avoiding or even reverting the temperature trend might be required. This

Poly(N-isopropylmethacrylamide) (PNIPMAM) is a stimuliresponsive polymer, which in thin film geometry exhibits a volume-phase transition upon temperature increase in water vapor. The swelling behavior of PNIPMAM thin films containing magnesium salts

Temperature control of rheological properties of aqueous solutions can be achieved by the addition of amphiphilic polymers that show temperature-dependent self-assembly. For this purpose, we explored three sets of acrylamide-based block copolymers wi
