UV Light to Heal Scratches
Extraordinary Science
A special polymer has been developed at Case Western Reserve, that changes its structure when exposed to UV light. This polymer is made up of lots of tiny molecular chains that are held together with a glue of metallic ions.The metallic ions stop acting like a glue upon use of a UV light, and the chains separate into a liquid that fills in any cracks. Believe it or not, the process happens so fast that it will be good as new in about 30 seconds.
