Lafont, U.L. (author), Van Zeijl, H.W. (author), Van der Zwaag, S. (author)While conventional self healing materials focus on the restoration of mechanical properties, newer generations of self healing materials focus on the restoration of other functional (i.e. non-mechanical) properties. Thermal conductivity is an example of an important functional property of a Thermal Interface Material (TIM) for LED’s and...conference paper 2013

Osada, T. (author)Self-crack-healing behaviors in alumina/ silicon carbide (SiC) nanocomposites (agent diameter of 270 nm) having the semi-eliptical surface crack were investigated at various healing temperatures TH and oxygen partial pressures pO2 in standard pressure. The results showed the complete strength recovery was attained by heating at test temperature...conference paper 2013

Jonkers, H.M. (author), Palin, D. (author), Flink, P. (author), Thijssen, A. (author)Concrete constructions in the marine environment suffer from chemical attack of sea salts which can induce damage to both the concrete matrix and embedded steel reinforcement. For example, ingress of sulfate and chloride ions can respectively result in detrimental ettringite formation and enhanced corrosion of the steel rebars. The first...conference paper 2013

Su, J.F. (author), Qiu, J. (author), Schlangen, H.E.J.G. (author)Preservation and renovation bitumen of pavement is a big problem for the whole world. Traditionally, application rejuvenators is the only one method that can restore the original properties of the pavements. However, some puzzles still restrict its successful usage. Microencapsulation is a promising method to apply rejuvenator in bitumen. These...conference paper 2013

Bose, R.K. (author), Garcia Espallargas, S.J. (author), Van der Zwaag, S. (author)Supramolecular rubbers based on 2-aminoethylimidazolidone and fatty acids with epoxy crosslinks have been shown to self-heal via multiple hydrogen bonding sites. In this work, several tools are used to investigate the molecular mechanisms taking place at the interface to understand cohesive healing in these polymers. The quantification of self...conference paper 2013

Vega Vega, J.M. (author), Van der Zwaag, S. (author), Garcia Espallargas, S.J. (author)Poly(ethylene-co-methacrylic acid) (EMAA) ionomers have shown healing capabilities in both ballistic and static tests. In previous studies it was shown that the degree of crosslinking (clusters) affects (positively or negatively) the healing under impact tests. Moreover, it has also been reported that the modification of the ionomers by...conference paper 2013

Latsuzbaia, R. (author), Negro, E. (author), Koper, G.J.M. (author)Platinum nanoparticles, which are used as catalysts in Proton Exchange Membrane Fuel Cells (PEMFC), tend to degrade after long-term operation. We discriminate the following mechanisms of the degradation: poisoning, migration and coalescence, dissolution, and electrochemical Ostwald ripening. There are two ways to tackle this problem. The first...conference paper 2013

(author)In the present research a test procedure was set up to reproduce self-healing on lime-based (both pure calcium and magnesium-calcium) mortar specimens in laboratory. After few months testing, during which the specimens were subjected to wet-dry cycles, thin sections of the specimens were prepared and observed by Polarization and Fluorescence...conference paper 2011

These materials can be large-scale processed using printing and coating on rigid and flexible substrates. The resulting devices can therefore be fabricated at low cost for various applications. Production yields suffer,...conference paper 2013

Song, Y.K. (author), Chung, C.M. (author)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...conference paper 2013
