What are self -healing materials?
Self -leakage materials are substances that are able to automatically repair structural cracks or other damage, a ability that can significantly extend the usable life of the product, and in some cases helps protect people from damage. Many self -fixing products have been inspired by biological processes that allow living bodies to heal. By observing the natural healing of activity at the microscopic level, scientists develop several methods to replicate this beneficial ability in substances caused by man. There are several different types of self -healing products and multiple approaches can be used to create these materials. Regardless of the structure, all repair objects are designed to work without requireing human intervention.
One type of self -repair product is known as a microencapped system. These self -healing materials are specially designed to repair small cracks that occur in polymers. This damage, sometimes called "microcrocking", canthat be caused by mechanical wear or thermal tension. The microcapsulated materials contain a chemical agent that is formulated for the reconstruction and strengthening of the polymer structure. The epoxy layer contains these reinforced chemicals in small pockets and the agent begins to spread when structural damage causes the small capsules to rupt.
microvascular systems are another variety of self -leaking materials. Like microenculated solutions, this type of material uses the healing agent that is maintained until it is needed. Instead of spreading evenly over the surface in small capsules, however, useful chemicals are placed in artificial "veins" or channels that exceed the material. This vein -like structure allows chemicals to be pumped in a cracked area, helping to prevent continuous damage.
The third method that can be used to create self -healing materialours, uses mechanicmically active polymers. This approach is similar to the way the human bones begin to repair after breaking. With this method, polymers that contain clusters of molecules are created and are called "mechanophores". These clusters are naturally susceptible to connection with other similar molecules. When the polymer is influenced by the voltage, the built -in mechanophores form a structural connection, similar to the two pieces of dry eyelashes are forced together.
Self -leakage materials have many practical applications. Scientists experimented with spacecraft surfaces that automatically seal dangerous rupture caused by meteoroid strikes or spatial fragments. The aircraft can also benefit from these substances and can benefit from cracks resistance on control surfaces. These types of materials can also be used in synthetic rubber products to prevent the life of the tread.
