Researchers 'color code' webbing material for exposure to damaging UV rays

A new study sheds light on a photochromic nylon webbing that, because it comprises spiropyran (SP) functionalized polymers, demonstrates color variation in response to extended UV exposure with controlled, color variation over multiple time scales that is conducive to UV sensing. The find could lead to new ways to estimate UV damage to materials.
