Self-healing materials are a class of smart materials which are inspired by biological systems. They have a structurally incorporated ability to repair damage caused by mechanical usage over time. A material that can intrinsically correct damage caused by normal usage could lower costs of different industrial processes through longer part lifetime, reduction of inefficiency as well as prevent costs incurred by material failure. They were first observed during roman times in mortars however their development began only at the close of the 20th century. It is a well-known fact that the initiators for structural failures include micro cracking and hidden damages. Repairing at remote locations is taxing and not easy or convenient. This is where self-healing materials have a great potential, thereby increasing the longevity of the structural materials. The property possessed by self-healing materials have a wide range of applications such as self-healing space crafts, satellites, used for geographical studies, GPS and in Automotive industries.Whenever a living organism experiences a superficial injury like a cut or a bruise, the defence system kicks in and forms a protective layer over it called a scab to begin the repair process. Self-healing materials are analogous to these systems. They have the ability to condition the mechanical damage incurred during any operation. There is tremendous growth in investments being made from both government and private industries.
