摘要: We report the synthesis and characterization of a healable, elastomeric shape recovery supramolecular polyurethane whose properties result from self-complementary π–π stacking hydrogen bonding interactions plus phase separation. ESEM analysis photographic images have revealed that this material can heal at 45 °C in 15 min to recover mechanical pristine with healing efficiencies >99%. This is also able an applied strain 25% within 5 release load.
