Abstract

The search for suitable strategies to manufacture self-healable nitrile rubber (NBR) composites is the most promising part in the industrial field of polar rubber research. In recent years, some important strategies, specifically, metal-ligand coordination bond formation, ionic bond formation, and dynamic hydrogen bond formation, have been utilized to develop duly self-healable NBR composites. This paper reviews the continuous advancement in the research field related to self-healable NBR composites by considering healing strategies and healing conditions. Special attention is given to understand the healing mechanism in reversibly cross-linked NBR systems. The healing efficiency of a cross-linked NBR network is usually dependent on the definite interaction between functional groups of NBR and a cross-linking agent. Finally, the results obtained from successful studies suggest that self-healing technology has incredible potential to increase the sustainability and lifetime of NBR-based rubber products.

摘要

寻找制造可自修复丁腈橡胶（NBR）复合材料的合适策略，是极性橡胶研究工业领域中最具前景的部分。近年来，一些重要策略，具体而言，金属-配体配位键形成、离子键形成和动态氢键形成，已被用于开发适当的可自修复NBR复合材料。本文通过考虑修复策略和修复条件，综述了可自修复NBR复合材料相关研究领域的不断进展。特别关注理解可逆交联NBR体系中的修复机制。交联NBR网络的修复效率通常取决于NBR官能团与交联剂之间的特定相互作用。最后，成功研究获得的结果表明，自修复技术在提高基于NBR的橡胶产品的可持续性和使用寿命方面具有巨大潜力。
