摘要

The long application life and stable performance of stretchable electronics have been putting forward requirements for both higher mechanical properties and better self-healing ability of polymeric substrates. However, for self-healing materials, simultaneously improving stretchability and robustness is still challenging. Here, by incorporating sliding crosslinker (polyrotaxanes) and hydrogen bonds into a polymer, a highly stretchable and self-healable elastomer with good mechanical strength is achieved. The elastomer exhibits very high stretchability, such that it can be stretched to 2800% with a fracture strength of 1.05 MPa. Moreover, the elastomer can achieve nearly complete self-healing (93%) at 55 degrees C. Next, tensile tests under different temperatures, step extension experiments, and in situ small angle X-ray scattering confirm that the excellent stretchability is attributed to the combined effects of sliding cyclodextrins along guest chains and hydrogen bonds. Furthermore, a strain sensor by coating the single-wall carbon nanotubes onto the surface of the elastic substrate is fabricated.
