Researchers develop new plastics that 'bleed' and heal like human skin
It looks like plastics may not be something for the squeamish in the not-too-distant future. Researchers from the University of Southern Mississippi recently revealed a new type of plastic they've been working on that takes its inspiration from human skin -- it "bleeds" red when it's scratched or cut and then heals itself when it's exposed to light. As Popular Science notes, self-healing plastics aren't something entirely new, but the "bleeding" (achieved using small molecular links or "bridges" that break when the plastic is scratched) is, as is the fact that this plastic can heal itself over and over again in the same spot. What's more, as it's made from water-based copolymers, it's also more environmentally-friendly than other plastics. Of course, it's all a ways from being used in actual products, but the researchers see no shortage of possibilities, including everything from self-healing car fenders to aircraft applications that could warn of problems before they get too severe.
