Activity 14: Physical and Chemical Properties of Materials
... • A property is a quality or trait that characterizes a material or object. • Physical Properties can be determined without a chemical reaction. • Chemical Properties can only be determined by looking for a reaction. • Chemical Reaction is when a substance changes chemically into another substance. ...

Self-healing material
Self-healing materials are a class of smart materials that have the structurally incorporated ability to repair damage caused by mechanical usage over time. The inspiration comes from biological systems, which have the ability to heal after being wounded. Initiation of cracks and other types of damage on a microscopic level has been shown to change thermal, electrical, and acoustical properties, and eventually lead to wholescale failure of the material. Usually, cracks are mended by hand, which is unsatisfactory because cracks are often hard to detect. A material that can intrinsically correct damage caused by normal usage could lower costs of a number of different industrial processes through longer part lifetime, reduction of inefficiency over time caused by degradation, as well as prevent costs incurred by material failure. For a material to be strictly defined as self-healing, it is necessary that the healing process occurs without human intervention. Some examples shown below, however, include healing polymers that require intervention to initiate the healing process.
