The deterioration of organic coatings on concrete is closely linked to the efficiency in the protection process of reinforced structures. In the present work, polyurea resin and epoxy resin, which are widely used engineering coatings, were selected to measure and compare the performance under artificial aging. Fourier Transform infrared...

Encapsulation of reactive agents embedded within a matrix is the most studied concept to develop self-healing materials. The most common approaches employ either a single component with catalyst dispersed in the matrix or a single environment-reactive component for corrosion protection [1]. Recently an approach for corrosion protection based on...

Commonly coatings are used to protect metals from corrosion. Different types of coatings are available and according to their characteristics they provide different levels of protection. In order to evaluate the performance of the coating, it is fundamental to have a methodology that is reliable and efficient even when applied to different kinds...

Recently, encapsulated silyl esters have been shown to act as efficient healing agents for self-healing anticorrosive coatings. While the positive protective effects were irrefutable, the actual protection mechanism has not been clarified yet. In this study, x-ray computed ?-tomography and electrochemical impedance spectroscopy have been...

Previously, we reported a self-replenishing polymer surfaces which recover their lowsurface energy (i.e. hydrophobicity), upon surface damage[1]. Following up, we used a dual experimental-simulation approach to understand in-depth the surface segregation of low surface energy components[2], the self-healing mechanism involved on the surface...

A protective coating is used to protect surface of a material from various deterioration factors. When cracks form and propagate in the coating, water, chloride ion, and carbon dioxide would penetrate through the cracks. This results in the deterioration of the material, leading to reduction in its serviceability. If the protective coating has...

Crack healing in ceramic thermal barrier coatings (TBCs) may be realized by embedding Mo-Si based particles in the thermal barrier coating. Upon cracking, these particles are exposed to oxygen that permeates through the top layer and the crack gap is filled with SiO2 which is produced from oxidation at high temperature. Due to its amorphous...

In the last decade several intrinsic self-healing materials have been developed in which the healing mechanism was mainly based on the reversibility of a certain structural element. For this purpose, reversible covalent bonds, e.g., based on the Diels-Alder reaction or weaker non-covalent interactions, e.g., hydrogen bonding, ionic interactions...

Among the different alternative surface treatments developed in view of the coming prohibition of chromates in aeronautic applications, sol-gel coatings show very promising properties. These layers provide a barrier against aggressive environments. Moreover, their performance can be improved by introducing inhibitive agents in the coating....

Self-healing materials allow for a design concept based on damage management where damage that is inflicted during operation can be healed autonomously. It has been shown that the Mn+1AXn phases Ti3AlC2, Ti2AlC and Cr2AlC exhibit autonomous self-healing behaviour. Cracks are filled and hence healed by oxidation products of the M and A elements...

A supramolecular material exhibiting self-healing properties was studied in this work. The material is based on the mixture of two ABA-type oligomeric triblock copolymers, the first consisting of positively charged end blocks and the second one of negatively charged ones. Each oligomeric triblock consists of a soft middle block and soft end...

Hydrophobic materials hold many properties that are desirable in coatings, e.g. water repellency and low-adhesion are essential to achieve an easy-to-clean/ self-cleaning behavior. However, most of the coatings currently available cannot maintain their hydrophobicity upon surface damage or wear, due to the irreversible loss of the low surface...

A self-healing corrosion protective coating was developed using TiO2 particles and casein as pH-sensitive organic agents that is also environmentally friendly materials. A film structured of TiO2 particles was formed on a substrate (magnesium alloy) by dip-coating followed by immersion in a casein solution. Casein was inserted and fixed in the...

Impressed current cathodic protection (CP) based on pulse technology has been proven to be a more efficient and effective alternative of traditional CP for reinforced concrete applications. Essentially, the superiority of pulse CP is in achieving the required steel polarization with otherwise reduced side effects (e.g. influence on bond strength...

Self-healing materials have the capabillity to repair (in an early stage) damage, that would finally lead to material failure. This repair or self-healing occurs with the help of a minor external stimulus or autonomously. Depending on the type of application one or the other is more interesting. Nature is the major source of inspiration for his...

Self-healing can be achieved in polymer coatings by the incorporation of extrinsic materials, i.e. a healing agent is embedded into the coating (e.g., within capsules). In contrast the polymeric coating itself can feature the ability for healing – for instance if reversible covalent bonds are introduced into the polymer network. The Diels-.Alder...
