SUMMARY

The scientific objective of the project consists in preparation of smart mesoporous silica nano-containers capable of stimuli-responsive release of the encapsulated corrosion inhibitors (CIs), as key components for obtaining superhydrophobic silica hybrid coatings with enhanced anticorrosion active protection for metallic surfaces.


OBJECTIVE

The strategic objective of the project respond to the need to accomplish the estimated results of the RESEARCH PROJECTS FOR YOUNG INDEPENDENT TEAMS - PN-III-DCD-RU-TE-2019-2, entitled: "New Intelligent Anti-Corrosion Coatings for Active Protection of Metallic Surfaces, Enhanced with Stimuli - Responsive Mesoporous Silica Nanocontainers Loaded with Organic Inhibitors" are: to develop ability of the young researchers to lead teams and manage research projects and to increase their capacity to implement their own research program. Thus, the proposal aims to create an additional opportunity to strengthen a young research team and an independent research program for it, providing the financial and logistic support necessary for 2 young researchers, 2 postdoc students; 3 PhD students and 1 master's student to carry out their own research activities and to enable them to achieve international high-level of scientific research. The scientific objective of the project consists in preparation of smart mesoporous silica nanocontainers capable of stimuli-responsive release of the encapsulated corrosion inhibitors (CIs). They will be used as key components for obtaining superhydrophobic silica hybrid coatings with enhanced anticorrosion active protection for metallic surfaces. Optimization of mesoporous silica nanoparticles as pH-triggered opening nanocontainers, Design and preparation of of superhydrophobic film forming silica matrices by a simple sol-gel route in the presence of different nanofillers with oxigen barrier and anticorrosion properties and Optimization of the anticorrosion coatings with integrated nanocontainers will be analyzed in terms of the efficiency of the corrosion resistance of the metal surfaces they cover.
