Generally, materials will degrade over time due to fatigue, environmental conditions, or damage incurred during operation. Repair of certain materials during their lifecycle (especially those with structural functions such as concrete) can be very expensive and labour intensive. Therefore Scientists began developing self-healing materials , those artificial (synthetic) substances that …
