Surface Engineering of Biomimetic Antibacterial and Biocompatible Hybrid Materials Through Molecular Layer Deposition

Resumen

First part of this thesis highlights a new method for obtaining ultrathin conformal films composed of chitin and chitin-based organic-inorganic hybrid biomaterials from the gas phase by molecular layer deposition (MLD). The second part of this thesis investigates silicon-based films with application potential in packaging or further biomedical applications. MLD growth of a new materials group of hybrid alumosilazane films was explored For the first time synthesized from the vapor phase by utilizing a ring-opening reaction of V3N3 and coupling it with TMA was obtained. The last chapter of the thesis reports on the first gas-phase solvent-free synthesis of Polyoxazolines via living cationic ring-opening polymerization. For this a new type of MLD process has been developed, which uses TosCl chloride as initiator for polymerizations of 2-methyl-2-oxazoline, 2-phenyl-2-oxazoline and 2-isopropenyl-2-oxazoline.
