AB  - Combining stretchability and self-healing properties in a man-made material is a 
      challenging task. For an efficient self-healing material, weaker dynamic or 
      reversible bonds should be presented as crosslinks so that they will first break 
      upon damage and then reform after healing, which is not favorable when developing 
      elastic materials. In this work, by incorporating dynamic Fe(III)-triazole 
      coordination bonds into polydimethylsiloxane (PDMS) backbone, a highly elastic 
      polymer is obtained that can be thermally healed at mild temperature. The 
      as-prepared polymer can be stretched to 3400% strain at low loading speed (1 mm 
      min(-1) ). When damaged, the polymer can be thermally healed at 60  degrees C for 20 h 
      with a healing efficiency of over 90%. The good mechanical and healable 
      properties of this polymer can be ascribed to the unique coordination bond 
      strength and coordination conformation of Fe(III)-triazole coordination complex.
