The scratch-proof car: Scientists create coating that repairs itself in the sun in 30 minutes

Scientists claim to have invented a 'self-healing' coating that repairs scuffs or blemishes on paint when exposed to sunlight.

Revolutionary: Repairing scratches on car paint soon won't be necessarily as a plastic is being invented that can heal itself when exposed to sunlight

Polymer Coating Heals Itself

Biswajit Ghosh and Marek W. Urban of the University of Southern Mississippi have come up with another approach, which they describe in a paper in Science. With their method, what breaks is not a sphere, but a ring-shaped chemical, oxetane, that is incorporated in the polyurethane polymer. Another compound in the polymer, chitosan, forms cross-links at the places where the oxetane breaks, healing the scratch.

Cracks repair in 30 minutes

The team demonstrated that a hairline crack - around 10 micrometres in thickness - could be completely knitted back together under bright UV light in around 30 minutes. However, they have not yet investigated more complex damage or deeper scratches.
