ABSTRACT
The proposal aims to improve the corrosion inhibition performance of porphyrins and pseudo-binary oxides, including new design of structures and several possibilities to combine them in complex layers by using pulse laser deposition technique, for creating synergistic effect on carbon steel protection in acid media. The project is multidisciplinary and belongs to the sustainable physics, laser technologies, inorganic and organic chemistry, supramolecular chemistry, electrochemistry and environmental sciences. The approach for the obtaining of new A3B COOH-substituted-porphyrin-base structures and of MnTa2O6 pseudo-binary oxide will be based on both modern and conventional methods, namely: multicomponent Adler-Longo organic synthesis using two different substituted aromatic aldehydes for porphyrins and hydrothermal or solid-state methods for the oxide. The main objective is innovative, a priority of our group to combine supramolecular properties of A3B porphyrins asymmetrically substituted with COOH groups with those of Mn containing pseudo-binary oxide in designing hybrid composite thin films (single layer or double layers type: steel / porphyrin / MnTa2O6 or steel / MnTa2O6 / porphyrin) for reducing the rate of corrosion. The project promotes both industrial oriented and applicative research, together with technological development (PLD) in realization of qualitative uniform and adherent corrosion protection layers. The whole pioneering concept belongs to the three teams composing this CONSORTIUM and it was established based on the main required expertise of the partners in order to cover all the demands for achieving the project’s activities. The project will develop at TRL 2 and will be ended with a model/prototype on real steel samples demonstrating the integrated system validity (TRL 4) during laboratory tests. Scientific (visibility), financial (reduced costs) and transfer to industry (patent application) impacts are expected along with creation of new collaborations.
