Hierarchically structured polymer blends based on silsesquioxane hybrid nanocomposites with quaternary ammonium units for antimicrobial coatings

► Hierarchical assemblies with silsesquioxane and quaternary ammonium units. ► Silsesquioxane-based polymer blends as antimicrobial/antifungal coatings. ► Antimicrobial/antifungal activity - primarily influenced by the nanotopography.
