Scientists Make Self-healing RubberSelf-healing materials are not exactly rocket science in 2015, but the Leibniz-Institut für Polymerforschung, Technische Universität Dresden, and Tampere University of Technology took things up a notch in the right direction. Until now, the chemical cross-linking of rubber by sulfur vulcanization was the only method to manufacture automobile tires, even Pirelli P Zeros. But Amit Das and his Leibniz Institute for Polymer Research buddies developed an all-new type of rubber that can heal itself. Be it a puncture, tear, or even a break, the rubber presented in the following video can heal itself, so you and I don'
;t have to break out that spare tire ever again.
Through something called "imidazolium-modified BIIR," rubber can form a cross-linked network of ionic association. Through this chemical reaction, ions of opposite electrical charge come together to form a new chemical entity. As a result of opposing each other, ions make the rubber matrix become highly elastic, without adding sulfur or peroxides to the material'
;s formula. Compared to conventional rubber, the tensile strength of this self-healing rubber is up to 9 MPa at a fracture elongation of 1,000%. Wait, come again? #tech #future #tire
