Digital photo and mechanical properties of the stretchable polyurethane acrylate elastomer. Digital photo of the PUA elastomer at strains of a 0% and b 3000%. Scale bar: 5 mm. c Schematic illustration of the breaking and reforming of hydrogen bonding resulting in high stretchability. d Tensile stress–strain behavior of the polyurethane acrylate (PUA) film. e Tensile loading and unloading data of the PUA for evaluation of its hysteresis behavior. f Stress–strain behavior of the self-healed PUA film with different healing time at 100 °C. Deformation rate for all measurements: 100 mm min−1
