In recent years, formation of a multitude of smart coatings made from macromolecular building blocks has been demonstrated. Typical examples are brush type architectures or films formed by layer-by-layer self assembly (LbL-SA). In our work, we investigate multicompartment micelles formed from amphiphilic ABC triblock terpolymers as building blocks for responsive coatings. The application of such colloidal units for thin films has several advantages from a material-science perspective, e.g. stimulus-responsivity and multi-functionality on a single particle level and simple preparation of coatings by physisorption. Besides, using LbL-SA allows forming hierarchically structured coatings with novel properties and collective stimulus response of the integrated nanostructures.[1] Here, we investigate the effects of pH and salt on properties of these films [2] and explore the accompanying morphological changes of the surface immobilized micelles as a function of their composition, i.e. properties of each block and the succession they are connected to each other. 1.Gensel J., Dewald I., Erath J., Betthausen E., Müller A.
