| 3 | A topological polymer network with Cu(Ⅱ)-coordinated reversible imidazole-urea locked unit constructs an ultra-strong self-healing elastomer显示文摘It is exceedingly desired, but difficult to construct self-healing materials with both excellent mechanical properties and healing efficiency, which are usually realized by using mutually exclusive methods. Here, we reconcile this contradiction by utilizing copper-bis-(imidazole-2-yl)-methane-urea(Cu-BIMU) locked units based on novel designed dynamic imidazole-urea bonds with coupled multiple noncovalent bonds(coordination bonds, π-π stacking bonds, and hydrogen bonds). The coordination of Cu(II) greatly reduces the electron-cloud density of imidazole, which lowers the free energy barrier of imidazole-urea bonds and promotes their reversible dissociation, as demonstrated by the density functional theory and small-molecule model reaction. The topological design of Cu-BIMU polyurethane(Cu-BIMU-PU), which concentrates multiple crosslinking-in-one locked unit to avoid the formation of excessive crosslinking sites to ensure high chain mobility, facilitates self-healing. Accumulative extensive intermolecular interactions endowed excellent mechanical properties to the resulting Cu-BIMU-PU elastomer with a tensile strength of 65.3 MPa, among the highest ever-reported value. This work provides a novel molecular design principle for fabricating high-performance dynamic polymers. | Lei Yang Zenghe Liu Rasoul Esmaeely Neisiany Jiaming Lou Yifan Guo Luzhi Zhang Huijie Liu Shuo Chen Shijia Gu Zhengwei You | 2023 | Science China Chemistry2023，66，3： | 0 |
| 4 | Peptidoglycan-inspired autonomous ultrafast self-healing bio-friendly elastomers for bio-integrated electronics显示文摘Elastomers are essential for stretchable electronics,which have become more and more important in bio-integrated devices.To ensure high compliance with the application environment,elastomers are expected to resist,and even self-repair,mechanical damage,while being friendly to the human body.Herein,inspired by peptidoglycan,we designed the first room-temperature autonomous self-healing biodegradable and biocompatible elastomers,poly(sebacoyl 1,6-hexamethylenedicarbamate diglyceride)(PSe HCD)elastomers.The unique structure including alternating ester-urethane moieties and bionic hybrid crosslinking endowed PSeHCD elastomers superior properties including ultrafast self-healing,tunable biomimetic mechanical properties,facile reprocessability,as well as good biocompatibility and biodegradability.The potential of the PSeHCD elastomers was demonstrated as a super-fast self-healing stretchable conductor(21 s)and motion sensor(2 min).This work provides a new design and synthetic principle of elastomers for applications in bio-integrated electronics. | Luzhi Zhang Jiahui Liang Chenyu Jiang Zenghe Liu Lijie Sun Shuo Chen Huixia Xuan Dong Lei Qingbao Guan Xiaofeng Ye Zhengwei You | 2021 | National Science Review2021，8，5： | 0 |
