Strategies for developing multi-functional, self-healing coatings for corrosion prevention and other functions

Photodegradation of 2-mercaptobenzothiazole and 1,2,3-benzotriazole corrosion inhibitors in aqueous solutions and organic solvents

“…The utilization of inhibitors for the minimizing of metal corrosion attracts an increasing interest 1,2 . The area of selfhealing protective coatings, involving the anti-corrosion inhibitors is developing very fast in the last decade due to the strong industrial demand [3][4][5] . One of the main strategies is based on the incorporation of inhibitor compounds into polymer, hybrid or inorganic layers 6,7 .…”

Impact of Surface Topography, Chemistry and Properties on the Adhesion of Sodium Alginate Coatings Electrophoretically Deposited on Titanium Biomaterials

“…However, these papers contain little information about the adhesion of coatings to metallic substrates and no information about the influence of the substrate preparation before the deposition on the coating adhesion. It is well known [20,[25][26][27][28][29][30][31] that the adhesion of the coating to an underlying material is beneficial from the application point of view of the coated material. It decides on the durability of the coating/substrate system and is highly dependent on the surface condition of the base material.…”

“…[26] The adhesion of coatings to metallic substrates is a complex phenomenon that depends on various factors, such as chemical and phase composition of the substrate, surface roughness and topography, surface free energy and wettability, surface charge, and substrate purity or the presence of defects. [27][28][29][30][31] Besides this, the physical properties of both the substrate and coating materials are of great importance, particularly the thermal and elastic mismatch between the coating and the substrate and the coating thickness. [26] Thus, the excellent organic sodium alginate coating adhesion should be foreseen from both optimised chemistry enabling covalent bonding of the coating to the titanium substrates and surface topography features enabling mechanical interlocking of the coating.…”

Heterostructured TiO2/SiO2/γ-Fe2O3/rGO Coating with Highly Efficient Visible-Light-Induced Self-Cleaning Properties for Metallic Artifacts

“… 9 − 13 Besides, some of the general aspects of suitable coatings to preserve metallic historic and modern buildings exposed to harsh environmental situations are proper adhesion, chemical stability, colorlessness, and transparency to maintain the aesthetic characteristics of the original material. 14 …”

“…Indeed, its physicochemical properties, such as high chemical stability, easy availability, and the possibility to be easily added as coating or in mass to cementitious materials or to be deposited in the form of a thin film and reaching the superhydrophilic state, make it a great candidate for the preservation of metallic artifacts. The effect is that of reducing maintenance time and cost and protecting them from soiling by means of its self-cleaning features. − Besides, some of the general aspects of suitable coatings to preserve metallic historic and modern buildings exposed to harsh environmental situations are proper adhesion, chemical stability, colorlessness, and transparency to maintain the aesthetic characteristics of the original material …”
