Nissan and the University of Tokyo and Advanced Softmaterials Inc have come up with a self healing paint.
Scratch Shield was initially developed for Nissan and Infiniti cars but is now being used in the smartphone industry too.
This special paint is supposed to fill in minor scratches and blemishes. The paint is made from polyrotaxane, which means that when damage occurs to the coating, the chemical structure reacts to change back to its original shape and fill the gap.
