Self-healing coatings in anti-corrosion applications

Nonmetallic (based on polymers or oxides) and metallic protective coatings are used to protect metal products against the harmful action of the corrosion environment. In recent years, self-healing coatings have been the subject of increasing interest. The ability of such coatings to self-repair local damage caused by external factors is a major factor contributing to their attractiveness. Polymer layers, silica-organic layers, conversion layers, metallic layers and ceramic layers, to mention but a few, are used as self-healing coatings. This paper presents the main kinds of self-healing coatings and explains their selfhealing mechanisms.

“…[6] with permission from Elsevier properties can be improved by introducing 8-hydroxyquinoline (8HQ). This compound prevents the adsorption of chloride ions forming an insoluble chelate of aluminium [22]. There are also coatings consisting of PEI and poly(allylamine hydrochloride) and 2-(benzothiazol-2-ylsulfanyl)succinic acid [11].…”

“…When the local environment undergoes changes or if the corrosion process is started on the metal surface, the nanocontainers release encapsulated active material (inhibitor) directly into the damaged area, thus preventing undesirable leakage of the inhibitor and reduction of the barrier properties of the whole applied film (Zheludkevich et al, 2007;Andreeva et al, 2008Andreeva et al, , 2010Shchukin et al, 2008;Borisova et al, 2011). Recently, a review on smart coatings stresses the use of smart nanocontainers for the enhancement of active anticorrosion performance in protective coatings (Montemor, 2014).…”

Currently, the most promising approach in the corrosion protection of smart coatings is the use of nanoreservoirs loaded with corrosion inhibitors. Nanocontainers are filled with anti-corrosive agents and are embedded into a primer coating. Future prospective containers are halloysite nanotubes (HNTs) due to their low price, availability, durability, with high mechanical strength and biocompatibility. The aim of this work is to study the use of HNTs as nanocontainers for encapsulated dodecylamine for active corrosion protection of carbon steel. Halloysite clay was characterized by X-ray diffraction and TGA -thermogravimetric analysis techniques. HNTs were loaded with dodecylamine and were embedded into an alkyd primer with a weight ratio of 10 wt.%. The anti-corrosive performance of the alkyd primer doped with 10 wt.% of entrapped-dodecylamine halloysite was tested on coated carbon steel by direct exposure of the coated samples with a provoked defect into 0.01 mol/L NaCl corrosive media using electrochemical impedance spectroscopy (EIS) and scanning vibrating electrode technique (SVET). EIS and SVET measurements showed the self-healing properties of the doped alkyd coating. Coated samples were also evaluated in a salt spray chamber and the self-healing effect was unequivocally noticed.

“…Other novel works are focused on the use of assembled multilayer polyelectrolytes onto healing agents (corrosion inhibitors) by using layer-by-layer assembly which can be released on demand (external stimuli, pH, light, chemical reactions) [68]. In this sense, the pH-dependent self-healing of LbL deposited multilayer of weak and strong polyelectrolytes can be used as an effective anticorrosion protection system [69,70]. In addition, the development of superhydrophobic surfaces with self-healing is a very promising engineering approach.…”

This review reports the implementation of novel nanostructured functional coatings by using different surface engineering techniques based on wet chemistry. In the first section, the theoretical fundaments of three techniques such as sol-gel process, layer-by-layer (LbL) assembly and electrospinning will be briefly described. In the second section, selected applications in different potential fields will be presented gathering relevant properties such as superhydrophobicity, biocide behavior or applications in the field of optical fiber sensors.
