“…Moreover, the Young’s modulus of the elastomer is up to 340 MPa, which is the same as low-density polyethylene. On the other hand, we have also devoted to designing the fast self-healing elastomers with high mechanical strength [ 119 , 120 , 121 , 122 ]. In a previous work, a fast self-healing elastomer has been fabricated through the free radical polymerization using poly (ethylene glycol) 400 methyl ether acrylate (mPEG400-acrylate) and acryloylmorpholine (ACMO) as the raw materials, which exhibits a fast self-healing ability and high mechanical strength (only need 40 s to achieve complete healing with a tensile strength of 4.2 MPa as shown in Figure 10 ).…”

In the last few decades, self-healing polymeric materials have been widely investigated because they can heal the damages spontaneously and thereby prolong their service lifetime. Many ingenious synthetic procedures have been developed for fabricating self-healing polymers with high performance. This mini review provides an impressive summary of the self-healing polymers with fast self-healing speed, which exhibits an irreplaceable role in many intriguing applications, such as flexible electronics. After a brief introduction to the development of self-healing polymers, we divide the development of self-healing polymers into five stages through the perspective of their research priorities at different periods. Subsequently, we elaborated the underlying healing mechanism of polymers, including the self-healing origins, the influencing factors, and direct evidence of healing at nanoscopic level. Following this, recent advance in realizing the fast self-healing speed of polymers through physical and chemical approaches is extensively overviewed. In particular, the methodology for balancing the mechanical strength and healing ability in fast self-healing elastomers is summarized. We hope that it could afford useful information for research people in promoting the further technical development of new strategies and technologies to prepare the high performance self-healing elastomers for advanced applications.
