London -- The Royal Society of Chemistry has published a paper by Spanish researchers showing a self healing polyurethane elasatomer that can repair cuts to the bulk of the material.
The abstract says: "Aromatic disulfide metathesis has been reported as one of the very few dynamic covalent chemistries undergone at room-temperature. Here, bis(4-aminophenyl) disulfide is effectively used as a dynamic crosslinker for the design of self-healing poly(urea-urethane) elastomers, which show quantitative healing efficiency at room-temperature, without the need for any catalyst or external intervention.
The reasearchers, are based at the San Sebastian IK$-CIDETEC Research Centre, they are cited as Alaitz Rekondo, Roberto Martin, Alaitz Ruiz de Luzuriaga, Germán Cabañero, Hans J. Grandea and Ibon Odriozola*
