 | Self-healing rubber
The elasticity of conventional rubber is the result of macromolecular structures made up of very long molecules held together by strong bonds. Supramolecular chemistry helps manufacture rubber from small molecules assembled into a network by weak bonds, these molecules being derived from fatty acids of vegetable origin extracted from pine, sunflower or rapeseed. This supramolecular rubber has the ability to self-repair spontaneously time and again, with no thermal or mechanical stress required, and every time recovers its elastic deformation ability.
