“…Despite their clear advantages, such coatings have one major drawback: self-healing is possible only in the case of the first damage to the coating. Moreover, the incorporated particles may adversely affect the adhesion of the coating to the substrate [31,46,67,75,76]. In order to minimize this adverse effect, the micro/nanocontainer material should be matched to the coating material.…”

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.

“…4,5 In fact, selfhealing is currently one of the most active topics in materials science. [6][7][8] For polymers [9][10][11] and polymer coatings [12][13][14][15] several approaches have been reported to restore the integrity of the material, either by refilling the damaged areas, e.g., a) Electronic addresses: a.c.c.esteves@tue.nl and g.dewith@tue.nl via encapsulated reactive components (autonomous healing) or by reestablishing chemical bonds through reversible reactions triggered by external stimuli such as temperature, light or a pH switch (triggered healing). These approaches can use intrinsic healing concepts, [16][17][18][19] in which the healing agent is inherent to the material (i.e., is a part of the network or formulation) or extrinsic healing, where external components are added, such as filled capsules [20][21][22][23] or microvascular networks.…”

Nowadays, many self-healing strategies are available for recovering mechanical damage of bulk polymeric materials. The recovery of surface-dependent functionalities on polymer films is, however, equally important and has been less investigated. In this work we study the ability of low surface energy cross-linked poly(ester urethane) networks containing perfluorinated dangling chains to self-replenish their surface, after being submitted to repeated surface damage. For this purpose we used a combined experimental-simulation approach. Experimentally, the cross-linked films were intentionally damaged by cryo-microtoming to remove top layers and create new surfaces which were characterized by water Contact Angle measurements and X-Ray Photoelectron Spectroscopy. The same systems were simultaneously represented by a Dissipative Particles Dynamics simulation method, where the damage was modeled by removing the top film layers in the simulation box and replacing it by new "air" beads. The influence of different experimental parameters, such as the concentration of the low surface energy component and the molecular m...

“…Self-healing driven by film-forming of an encapsulated liquid is being widely investigated. There are encouraging results on self-healing of epoxy resins on AA2024 alloys by water-reactive silyl ester in urea-formaldehyde shells (García et al, 2011), sol-gel silica coatings on AA2024 alloys by methyl methycrilate in silica gel microcapsules , epoxy resins on carbon steel by epoxy binders in epoxy-amine shells , epoxy resins on carbon steel by linseed oil in ureaformaldehyde shells (Boura et al, 2012), and epoxy resins on carbon steel by tung oil in ureaformaldehyde shells (Samadzadeh et al, 2010). Liquid paints with capsules are also an active area of research, with most of the coatings applied with brush or drawer.…”

“…The healing mechanism is finished when the liquid, 'healant', solidifies through drying or polymerization, forming a protective layer between the damaged coated substrate and the corrosive environment. Self-healing materials are a combination of initiators, catalysts, and co-monomers that are present in the environment, in the paint matrix or are released from other types of capsules embedded in the same coating (Ghosh, 2006, Wu et al, 2008, Mauldin et al, 2010, Samadzadeh et al, 2010, Murphy et al, 2010. Certain types of functional paints are slow-release coatings that contain active agents entrapped in a usually solid matrix-structured carrier.…”

The mitigation of corrosion and biofouling is a challenge. Through application of chemicals and special techniques can slow these undesired processes, an effective resolution requires a multidisciplinary approach involving scientists, engineers, and metallurgists. In order to understand the importance of the use of nano-and microlayers as well as selfhealing coatings, the basic concepts of corrosion, corrosion mechanisms, corrosion inhibition and the microbiologically influenced corrosion will be summarised. The preparation, characterization and application of Langmuir-Blodgett and self assembled nanolayers in corrosive and microbial environment will be discussed. Preparation and characterization of microcapsules/ microspheres and their application in coatings will be demonstrated by a number of examples.Keywords: nano-and microcoating, self-healing, slow-release, anticorrosion, antifouling IntroductionCorrosion is a well-known problem all over the world. It consumes a significant part of the gross national product (GDP) of developed and developing countries. A number of authors have provided comprehensive introductions to corrosion mainly in aqueous and wet environments (Jones, 1991;Kaesche, 2003; McCafferety, 2010). Corrosion is the destructive result of the chemical/electrochemical reactions between metals and the environment. Corrosive reactions involve water in either liquid or condensed phases. Most corrosion reactions are electrochemical processes. These involve electron or charge transfer in aqueous solution which leads to metal dissolution (anodic reaction). Depending on the pH of the solution, either hydrogen or hydroxonium ions evolve, resulting in oxides, oxyhydroxides, hydroxides and salts formed on the metal surface (cathodic reaction). The electrochemical potential or electron activity affects the rate of corrosion reaction. To understand corrosion it is necessary to discuss briefly the types of corrosion and the reactions involved.Corrosion occurs in various forms.-Uniform corrosion: The metal surface must be compositionally uniform; the aggressive environment has the same access to all parts of the metal. This type of
