21st-century chainmail uses molecular instead of metallic links | The "highest density of mechanical bonds ever achieved," researchers created a flexible material that works like chainmail. The breakthrough has already demonstrated its ability to improve body armor.


In what they're calling the "highest density of mechanical bonds ever achieved," researchers created a super-strong flexible material that works very much like chainmail. The breakthrough has already demonstrated its ability to improve body armor.

More layers caused more monomers to spread and connect through the lattice, resulting in a series of loops all threaded together in a super-strong web akin to the metal links in chainmail. The researchers dedicated their study, which has been published in the journal Science, to Sir Fraser Stoddart, a former fellow Northwestern chemist who won the Nobel Prize in Chemistry in 2016 for his work pioneering mechanical bonds. "Molecules don't just thread themselves through each other on their own, so Fraser developed ingenious ways to template interlocked structures," said Dichtel, who was a postdoctoral researcher in Stoddart's lab at UCLA.
