Polymer Network Reconfigures in Sequence, Helping Elastomers Stay Tough Under Strain

Polymer network reconfigures in sequence, helping elastomers stay tough under strain

Shock-absorbing sneaker soles are likely made of polyurethane, a highly elastic and tough polymer. The ability of these elastomers to absorb impact without breaking is extremely important for practical applications. While multiple strategies exist for enhancing elastomer toughness, each has its limitations. However, achieving synergistic toughening by integrating all three mechanisms within a single material remains challenging.

Polymers Adapt Their Structure to Prevent Failure and Maintain Elastomer

In the dynamic world of materials science, the quest for developing elastomers that combine both exceptional softness and steadfast toughness has taken a significant leap forward. A team of innovative researchers at the University of Osaka has pioneered a groundbreaking approach to toughen elastomers—a class of highly elastic polymers widely used in everyday products such as shock-absorbing sneaker soles. Their novel methodology, detailed in the…
