Scholarcy highlights

  • Intrinsic healing materials based on reversible bonds possessing the unique adaptive properties of self-healing and recyclability have attracted considerable attention
  • One of the major challenges in intrinsic healing materials that remains is how to reinforce the mechanical property without sacrificing healing efficiency
  • Furfuryl-modified silica particles with high functional group grafting ratio and dispersibility, formed by sol–gel process, were introduced into the maleimide-terminated polyurethane elastomer to establish a thermo-reversible organic–inorganic network based on Diels–Alder reaction between furan@SiO2 and mPU
