En Route To Polymer That Heals Upon Squeezing
Researchers at the University of Illinois, Urbana-Champaign, have taken a first step toward making a material that responds directly to being damaged (J. Am. Chem. Soc., DOI: 10.1021/ja305645x). Self-healing polymers have been synthesized in the past, but many of those materials use encapsulated reagents or require external stimuli, such as light or heat, to initiate repair. To make the material, the Illinois researchers generated what they call a . . .
