Scientists develop new materials that allow cracks in buildings to repair themselves

Material scientists are developing new materials and hope that one day, aircraft and buildings will also have the ability to repair themselves just like human skin. This technology will be widely used in building bridges, making aircraft and building skyscrapers.

Reported that the toe fracture, the bone will slowly grow back, the knee accidentally bruises, the skin will gradually heal, but once the plastic, steel and concrete materials, such as damage, cracking or bending, is not difficult to repair, it is impossible Restore. But this situation will soon change. Material scientists are now actively exploring the regeneration and restoration capabilities of nature and trying to create materials that can repair themselves.

In the past few years, engineering scientists have used different strategies to solve this problem. But Sotos, an engineering expert at the University of Illinois, came to learn from human physiology and developed novel methods. Sotos was inspired by human skin to create plastics that can be repaired over and over again, paving the way for the development of materials that can cope with various environmental stresses.

This technology will reduce expensive repairs and inspections, but more importantly, it may also help prevent catastrophic failures and fatal consequences. Sotos said that material damage was usually not noticeable at first, but most buildings first appeared small cracks and then slowly collapsed without notice. She said, "The purpose of developing self-repair materials is to try to prevent these accidents and prevent these small cracks from becoming larger."

Sotos has designed plastics that can repair 50 cracks on their own, but creating materials that can be repaired like the human body remains one of the biggest challenges at this stage.
