Scientists observe interaction of components in tire rubber at the atomic scale

Posted by in categories: nanotechnology, physics, transportation

Scientists have observed the molecular motion of rubber components typically used in automobile tires—polybutadiene and carbon black—with the world’s fastest time resolution.

The study, published in Applied Physics Letters, reveals a clear interaction between the two components on the , paving the way towards improved diagnostics of tire rubber degradation and the development of materials with enhanced durability.

Tire rubber is a that typically includes , such as polybutadiene, and added nanoparticles, such as carbon black, to improve its . During driving, strong forces act on the tire, causing its components to move against each another, which can lead to wear and degradation of the material.
