“…Metals naturally corrode, which causes a reduction of their strength over time, potentially resulting in catastrophic failures. Organic coatings on metallic structures can be employed to isolate the metal from corrosive environments. , However, once the coating is damaged, it no longer protects the metal against corrosion. , The anticorrosion performance of coatings can be enhanced by loading corrosion inhibitors into the coating’s matrix. Indeed, corrosion inhibitors have the ability to protect the metal’s surface from corrosion attacks caused by the surrounding environment .…”

Nanostructured multilayered coatings for metals are prepared to simultaneously provide a function of corrosion mitigation and of corrosion sensing for copper substrates. Silica nanocapsules, embedded in one layer of the coating, are used as a host for a corrosion inhibitor and as a sensor, which detect changes of pH value and release inhibitors via an optical signal. Furthermore, another layer in the coating exists in a nanonetwork loaded with another corrosion inhibitor, which is impregnated with a hydrophobic polymer. We demonstrate that a specific arrangement of layers leads to an optimum anticorrosion and sensing performance while the sensing signal can be prolonged for a long time. It is the first time that the fluorophore detecting corrosion is conjugated to the nanosensor and that nanofibers and nanocapsules are used simultaneously to load and release corrosion inhibitors for anticorrosion applications.

“…One of them is Petrobras Specification N-2913 -Anti-corrosion coatings for carbon steel tanks, such as liquefied gas tanks and storage cylinders (CONTEC, 2015)which defines how corrosion protection coatings should be applied internally and externally to atmospheric tanks, liquefied gas tanks and cylinders in inland facilities. In the case of epoxy resin use inside storage tanks for chemical products, it is necessary to consider the possibility of interaction between the stored product and the epoxy (Shchukin et al, 2006;He et al, 2008;Baghdachi, 2009;Sørensen et al, 2009;Calle et al, 2010;Hamdy, 2010;Ganesh et al, 2011;Mathiazhagan et al, 2011;Choi et al, 2013;Makhlouf, 2014;Popoola et al, 2014;Ulaeto et al, 2017), from a chemical point of view (reaction between the coating and the stored product), and from a physical point of view (solubilization of some epoxy components or product penetration into its crystalline structure). Thus, taking into account the influence of each component from the epoxy coating and its interaction with aromatic hydrocarbons (benzene, toluene and xylenes) and using specific techniques to investigate the cause of interaction, the present study was carried out in order to adjust the epoxy coating formulation, resulting in experimental data that add significantly to the literature.…”
