New Plastic Heals Itself When Cut
A project harnessing squid genetics to develop a plastic that reattaches after it has been cut in two could be a significant advance for self-healing materials, according to a study published this month.
The squid-based polymer, shown in the gifs above, displays mechanical strength that can be recovered after the material is cut. All it takes is a drop of water, low pressure and some heat, and two pieces fuse back into one. The multinational team behind the research says their material could potentially make self-healing fiber-optic cables and medical implants.
“What’s unique about this plastic is the ability to stick itself back together with a drop of water,” said Penn State engineer Melik Demirel. “There are other materials that are self-healing, but not with water.” Learn more and see images below.
