'Self-healing' coating piques U.S interest

FRIBOURG, Switzerland (UPI) -- U.S. and Swiss scientists say they havedeveloped a polymer-based coating that can heal itself when placedunder ultraviolet light for less than a minute.

The "metallo-supramolecular" polymer coating has garnered interestfrom many parties, including the U.S military, Swissinfo.com reported.

"For the moment it's still at the basic research level," ChristophWeder, director of Fribourg University's Adolphe Merkle Institute,said. "We are not looking to develop products for the market butconcepts and tools that can then develop commercially viablematerials. That's the way our [nanoscience] institute functions."

He declined to comment on the U.S. military's particular interest inthe material.

"I don't want to speculate on their interest in supporting thisparticular project, but the people involved were really devoted tobasic research," said Weder, a Swiss professor of polymer chemistryand materials who has worked for many years in the United States.

The new material has many potential practical applications fromtactile computer screens to everyday consumer items like cars, floorsand furniture that get easily scratched.

"This is ingenious and transformative materials research," said AndrewLovinger, polymers program director at the National ScienceFoundation's Materials Research Division.
