Special Issue Information

Dear Colleagues,

Damage sensing materials can respond to structural damage by relying on their own characteristics to achieve early detection of minor damage. Microcapsule-based sensing technology including gel materials has been proposed and applied to damage monitoring of structures. Due to its flexible application and intuitive damage expression effect, it has received extensive attention in recent years. It provides the possibility to inspect subtle structural damage through visual signals.

The aim of this Special Issue is to understand the mechanisms of microcapsule-based sensing technology and to collect the latest research and achievements. In addition, we invite contributions concerning applications of microcapsule-based sensing technology. We hope that researchers working on these topics will provide valuable contributions to this Special Issue of Gels

Please note, the manuscripts submitted to this special issue should focus on the gel, gelling or gelation fields. More details can be found at https://www.mdpi.com/journal/gels/about.

A new type of concrete surface gel coating using thermosensitive fluorescent (TSF) microcapsules was proposed to monitor micro-cracks of cement-based materials. The gel materials can adhere other materials, and the incorporation of microcapsules into the gel coating can be cured on various structural surfaces. Zinc sulfide and phenyl acetate were encapsulated into a polymethyl methacrylate shell to prepare the TSF microcapsules by a solvent evaporation method. When micro-cracks are generated on the surface of the gel coating, the ruptured TSF microcapsules burst out, fill the damaged area, and then emit fluorescence after being excited at ambient temperature. It was found that the brightness of the fluorescence increased with increasing temperature from 80–110 °C. When the concentration of TSF microcapsules was 15% of the mass of the gel coating, the cement-based damage-sensing material had sufficient damage-indicating effects, and the fluorescence brightness of the crack location remained even after a long time. It is expected that this study will provide an effective and intuitive method for crack location detection of cement-based materials. Full article
