ABSTRACT
The materials corrosion, both regarding metallic and non-metallic ones, affects various economic fields, such as: cars industry, refineries, water pipeline systems, buildings and bridges. This has a blunt economical implication and every year immense costs are spent on capital replacement and control methods related to corrosion. Nowadays, much attention is given to the introduction of corrosion inhibitors for the protection of the technological equipment, thus providing both the significant decrease of steel corrosion in aggressive aqueous media and increasing the lifetime of expensive equipments.
Following this trend, the project proposal is focused on durable and applicative research, developing the knowledge in the advanced materials, processes and products which are innovative and realize an efficient protection against corrosion by using alternative processes for the thin films deposition (PLD and LBL drop casting) for achieving simple and sandwich type film configurations.
This will be achieved by designing of novel mixed nanostructured thin films from new ZnA2O6 (where A = Ta and/or V) pseudo-binary oxides and Zn-metalloprophyrins obtained from A3B free-porphyrins substituted by one pyridyl functional group. Choosing these structures is based on both Zn-pseudo-binary oxides and Zn-metalloporphyrins capacity to form self-oriented, adherent and continuous supramolecular architectures when deposited on steel surfaces.
The project belongs to the sustainable chemistry by proposing biomimetic porphyrin structures, and needs multidisciplinary approach, combining the different research areas: physics, organic chemistry, supramolecular chemistry, materials and environmental chemistry and electrochemistry.
