Elastomers

Definition

Elastomers are a class of polymers known for their elastic properties, meaning they can stretch significantly and return to their original shape after deformation. This unique characteristic makes them ideal for applications that require flexibility, durability, and resilience, such as in stretchable and self-healing materials, interconnects and circuits, as well as in flexible supercapacitors. Their ability to withstand mechanical stress while maintaining performance is crucial in the development of advanced electronic devices.
