摘要: Autonomous healing of damage is a common phenomenon in living organisms but hardly ever encountered synthetic materials. Disulfide chemistry used to introduce self-healing ability covalently cross-linked rubber. cut takes place at moderate temperatures and leads full recovery mechanical properties. This result achieved by introducing disulfide groups the network that are able exchange, leading renewal cross-links across damaged surfaces. The process can be repeated many times. combination their unique properties applicability for large variety polymers makes this approach ideal coatings.
