AI Article Synopsis
- A biodegradable version of epoxidized natural rubber (CNR) was created by reacting epoxidized natural rubber (ENR) with carbon dioxide, incorporating cyclic carbonate groups.
- The material features a unique double dynamic covalent structure formed through cross-linking with disulfide bonds and boronic ester, enabling high self-healing efficiency.
- This research marks the first successful development of natural rubber that combines both biodegradable and self-healing properties.
Article Abstract
In this paper, biodegradable epoxidized natural rubber containing cyclic carbonate groups (CNR) was prepared by the reaction between epoxidized natural rubber (ENR) and carbon dioxide. Dynamic disulfide bonds and a boronic ester structure were successfully constructed and then the cross-linking network was formed by the thermally initiated "click" reaction between thiol groups of the cross-linker and the residual epoxy groups of ENR. As a result of the exquisite double dynamic covalent structure, the material exhibits high self-healing efficiency. Moreover, by virtue of the cyclic carbonate structure of the CNR, the natural rubber was confirmed to be biodegradable according to the biodegradable measurement. To the best of our knowledge, natural rubber with biodegradable and self-healing characteristics was obtained for the first time.
