The development of self-healing materials is considered of great interest, both from a fundamental point of view and for engineering applications (aeronautics, electronics, composites, etc.). Over the past few decades, there has been a huge interest in materials that can self-repair, as this property can increase their lifetime, reduce replacement costs, and improve product safety. Recently, the supporting company MPB Technologies Inc. has demonstrated an innovative autonomous self-healing process, by adding microcapsules containing an ethylidene norbornene (ENB) monomer and a Ruthenium Grubbs Catalyst (RGC) within a polymer matrix. Our proposal seeks funds to address a problem of investigating the performance of an innovative self-healing material composite based on ENB mixed with nanomaterials additive, including carbon nanotubes (CNT) and ceramics nanopowder (SiC, SiN, SiO2), and integrated into suitable matrices for space debris protection. The objective is to provide novel composite materials and methodology suitable for the mitigation of space debris by absorbing the shock of the impact and healing the crater zone. More specifically, we propose a route towards the combination of the known higher mechanical properties of CNTs and ceramics nanopowder with the known fast ring opening metathesis polymerization (ROMP) rate inherent to the ethylidene norbornene (ENB) healing agent, thereby obtaining simultaneously a fast autonomic self repair damper composite with high mechanical properties.

自修复材料的发展被认为是非常感兴趣的，无论是从基本点， 视图和工程应用（航空、电子、复合材料等）。在过去的几十年里， 人们对能够自我修复的材料产生了巨大的兴趣，因为这种性质可以增加它们的寿命， 降低更换成本，提高产品安全性。近日，配套公司MPB Technologies Inc.已经展示了一种创新的自主自愈过程，通过添加含有 在一个实施方案中，所述方法包括在聚合物基质内的亚乙基二烯（ENB）单体和钌Grubbs催化剂（RGC）。我们 一项提案寻求资金，以解决调查创新的自我修复性能的问题。 基于ENB与纳米材料添加剂混合的材料复合物，包括碳纳米管（CNT）和 陶瓷纳米粉末（SiC、SiN、SiO2），并将其整合到适当的空间碎片防护基质中。的 目标是提供适合于减缓空间碎片的新型复合材料和方法 通过吸收撞击的冲击力和修复弹坑区域。更具体地说，我们提出了一条路线 朝向CNT和陶瓷纳米粉末的已知的更高的机械性能与 已知的快速开环易位聚合（ROMP）速率是亚乙基双烯所固有的 (ENB)愈合剂，从而同时获得快速自主自我修复阻尼器复合材料， 高机械性能。
