Spiropyran-functionalized photochromic nylon webbings show exposure to long-term ultraviolet light

Caption

The decay rate of nylon webbings' color demonstrated a dependence on the initial concentration of the SP dye. Webbings with the lowest dye concentration maintained sensitivity for four weeks; at the highest dye concentration, they exhibited sensing capability after eight weeks, suggesting dye concentration could be customized to meet the lifetime of the targeted applications.
