While self-healing polymers aren’t exactly a new technology, they’ve been suspiciously absent from consumer applications, especially in products that wear relatively quickly like smartphones. Excluding exploding iPhone screens, the most common type of damage a smartphone will get in its short lifespan will probably be a collage of nicks and scratches on the stock case. Hoping to change the game in terms of durability, LG will be the first to implement this type of material into its new G Flex Smartphone. In addition to a flexible curved shell, the phone’s backing boasts the ability to heal itself from scratches like the kind you’d get if you dropped your phone on concrete or accidentally left it in your pocket with your keys. Interestingly, and as the video will show, the polymer’s self-healing properties perform best in warmer temperatures, meaning that if you’re in colder conditions you can still accelerate the healing process by using body heat or friction.
