“…The capsules are filled in different ways, e.g. by agitating the suspension of capsules and fillers, also under reduced pressure, the soaking of capsules in inhibitor solution and by applying the LBL deposition procedure [27,54,56,70]. In the case of soaking encapsulation, different inhibitor retention mechanisms can be distinguished.…”

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.

“…Porous nanoparticles provide inhibitive effect upon pH-change when damaged sites are in contact with humidity. There are ceriumbased particles in carriers like chitosan [3], CeO 2 nanoparticles [4], hydroxyapatite- [5] and CaCO 3 [6] microparticles; mercaptobenzothiazole in layered double hydroxides [7] and polyelectrolyte nanocapsules [8] as well as benzotriazole in mesoporous silica particles [9]. Nanoparticles in general do not weaken significantly the mechanical properties and permeability of coatings [7,10,11,12], but their inhibition lasts only until the depletion of the nanocarriers.…”

Core-shell microcapsules of urea-resorcinol-formaldehyde shell and linseed oil (LO) core material as paint additives for self-healing coatings were prepared. The capsules contained LO either with or without Co-octoate as drier material and/or octadecylamine (ODA) as corrosion inhibitor. The microcapsules embedded in a commercial paint were applied on sandblasted mild steel sheets. After scratching the coated surface, the inhibition efficiency of core-shell microcapsule-containing coat, dipped into corrosive media, was followed visually and evaluated numerically by electrochemical impedance spectroscopy (EIS). In separate experiments, to optimize for the self-healing process, the composition of the core material, the effect of the drier and/or the inhibitor ODA on drying process of LO films were monitored by infrared spectroscopy. Pure LO needed 6-7 days to dry completely. The drying period could be shortened (to 5 h) via application of a dryer, but the addition of the corrosion inhibitor alone increased significantly the time needed for solifidicaiton. To minimize the drying period we have found the proper combination of the ODA and the dryer of the LO. The EIS measurements, in accordance with the drying tests, resulted in the next order of selfhealing ability: LO

“…They were mainly based on metal alkoxide systems particularly organosilanes and also merge with organic molecules, polymers and biocomponents. Especially aminopropyl functionalized silanes have vast interest and also have huge consideration.These materials achieve outstanding properties such as mechanical properties, thermal stability, degradation and abrasion resistance [2][3][4][5]. As a result, these polymer-inorganic hybrid materials have a lot of importance in the recent research.…”
