STRUCTURE AND HETEROGENEOUS DYNAMICS OF SELF-HEALING RUBBER FROM SUPERMOLECULAR ASSEMBLY AS REVEALED BY ADVANCED SOLID-STATE NMR
Supermolecular polymers have attracted tremendous attention in the last decade, their structure and dynamics are generally controlled or tailored by different kinds of weak interactions among chains. Self-healing polymer materials with excellent mechanical properties has broadly applied prospects in industry field, which has been a constant objective of materials scientists. Recently, Leibler et al. reported a novel type of self-healing rubber from supermolecular assembly of oligomers using renewable nature fatty acids and urea.12 A large number of complementary hydrogen bonds in the oligomer play an important role in controlling the unique self-healing property of this material. Although this novel material has attracted significant attention, the micro-structure, dynamics and its relationship with self-healing properties of this kind of novel material are still not well understood, detailed information about these issues needs to be further elucidated. In this work, we focused our attention on elucidating the multiscale microdomain structure and heterogeneous dynamics of the self-healing rubber on a molecular level by using a variety of advanced solid-state NMR (SSNMR) and other techniques. The effect of different components on the microstructure and macroscopic properties was obtained.
