The material eliminates scratches when exposed to sunlight.
A Korean research institute has created a transparent polymer coating that has the ability to self-repair if exposed to the sun for half an hour.
Scientists published the work in the scientific publication ACS Applied Polymer Materials.
A scratch on a car coated with the resulting polymer, tightens up without leaving a trace if the car is in the sun. Scientists explain this property of the material: absorbing sunlight, the polymer heats up, there is a reconstruction of the chemical bonds in the structure of the polymer.
Self-repairing material could be used in the future to cover equipment, building materials, electronics such as smartphones.
