How do you make adhesives for electronics, vehicles, and construction tougher?

23/03/2020

A Purdue University team, looking to make adhesives tougher, added bonds that are broken easily throughout the material. When pressure or stress is applied to the glue, these sacrificial bonds are designed to absorb energy and break apart. Meanwhile, the rest of the larger adhesive system remains intact.
