You read that right, researchers in Spain have developed a “Terminator polymer”, or one that is able to heal itself when torn apart and then put back togehter. Technically speaking, it’s a “permanently cross-linked poly(urea-urethane) elastomeric network.”
The science behind the scenes is a little complex and specific for the layman, but the results however, are easy to see. In just two hours of sitting around, the plastic can meld itself back together and recover 97 percent of a fully-severed connection.
No catalyst required. This is definitely Terminator-esque, but the practical uses for something like this are a little less murder-y, like more durable plastic components in cars, gadgets, and whathaveyou.
