Potential applications include durable tires, wearable electronics, medical devices. Imagine a tire that could heal after being punctured or a rubber band that never snapped. Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new type of rubber that is as tough as natural rubber but can also self-heal.
Self-healing materials aren’t new – researchers at SEAS have developed self-healing hydrogels, which rely on water to incorporate reversible bonds that can promote healing...
