Derelioglu, Z. (author), Ponnusami, S.A. (author), Turteltaub, S. (author), Van der Zwaag, S. (author), Sloof, W.G. (author)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...conference paper 2013

Bode, S. (author), Bose, R. (author), Sandmann, B. (author), Hager, M.D. (author), Garcia, S.J. (author), Van der Zwaag, S. (author), Schubert, U.S. (author)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...conference paper 2013

Recloux, I. (author), Olivier, M.G. (author)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....conference paper 2013

Berger, O. (author), Leyens, C. (author), Heinze, S. (author), To Baben, M. (author), Schneider, J.M. (author)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...conference paper 2013

(author)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...conference paper 2013

Zhang, Y. (author), Esteves, A.C.C. (author), Van der Ven, L.G.J. (author), Van Benthem, R.A.T.M. (author), De With, G. (author)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...conference paper 2013

Yabuki, A. (author), Sakai, M. (author)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...conference paper 2013

Mathis, C. (author), Garcia Espallargas, S.J. (author)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...conference paper 2013

De Vilder, I. (author), Vanneste, M. (author)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...conference paper 2013

Kötteritzsch, J. (author), Hager, M.D. (author), Schubert, U.S. (author)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...conference paper 2013
