A generalized silica coating scheme is used to functionalize and protect sub-micron and micron size dicyclopentadiene monomer-filled capsules and polymer-protected Grubbs' catalyst particles. These capsules and particles are used for self-healing of microscale damage in an epoxy-based polymer. The silica layer both protects the capsules and particles, and limits their aggregation when added to an epoxy matrix, enabling the capsules and particles to be dispersed at high concentrations with little loss of reactivity.
采用通用的二氧化硅涂覆方案对亚微米和微米尺寸的二环戊二烯单体填充胶囊和聚合物保护的 Grubbs' 催化剂颗粒进行功能化和保护。这些胶囊和颗粒用于修复基于环氧树脂的聚合物中的微尺度损伤。二氧化硅层既能保护胶囊和颗粒，又能限制它们在加入环氧树脂基体时的聚集，使胶囊和颗粒能够以高浓度分散，而不会损失其反应性。
