| 摘 要： | 通过简单的方法合成了一种兼具柔韧性和拉伸性的室温快速自修复磁性聚合物高分子。基于单分子磁体Mn12-Ac和含有脲键的聚二甲基硅氧烷高分子基底之间的氢键作用，该复合物材料展现了出色的磁性和室温快速自修复性质（修复时间为60 s，修复效率为99.5%）。这项工作将为磁性自修复材料在未来智能器件、响应型机器人等领域的应用提供更多的机会。

| Abstract: | In this work, a room temperature self-heling magnetic polymer which possesses excellent flexibility and stretchability was synthesized through a facile pathway. Based on the hydrogen bondings between single molecule magnet (SMM) Mn12-Ac and polymer matrix poly(dimethylsiloxane) (PDMS) containing urea groups, the resultant composite exhibits superior magnetic and fast room temperature self-healing abilities (healing time = 60 s, healing efficiency = 99.5%). This study will provide more opportunities of self-healing magnetic polymers for future applications in intelligent devices, responsive robots and other fields. |
