摘　　要：以脲醛树脂(UF)作为壁材,环氧树脂E-51(EP)作为修复剂,采用原位聚合法制备了自修复微胶囊,并采用硅烷偶联剂1H,1H,2H,2H-全氟葵基三甲氧基硅烷(KBM-7803)对壁材表面进行处理,加入环氧树脂中,固化得到改性微胶囊复合材料。通过傅里叶变换红外光谱(FTIR)、扫描电子显微镜(SEM)、激光粒度仪(PSDA)、电子万能试验机等分析测试技术对改性前后的微胶囊及改性微胶囊复合材料的微观形貌和自修复性能进行表征与分析。结果表明,所制备的微胶囊与基体材料相容性较好,当KBM-7803改性微胶囊的添加量为6wt%时,复合材料的自修复效率达到最高值77.4%,具有良好的自修复性能。Self-healing microcapsules were prepared by in-situ polymerization.using ures formaldehyde resin(UF)as the wall material and the epoxy resin E-51(EP)as the heal agent.The silane coupling agents KBM-7803 were used to couple the surface of the wall material in order to improve the compatibility between the microcapsules and the matrix.The microcapsules,modified microcapsules and self-healing composites were characterized by fourier transform infrared spectroscopy(FTIR),scanning electron microscopy(SEM)and laser particle size description analyzer(PSDA)in order to analyze their micro morphology and self-healing properties.The results show that the compatibility between the microcapsules and the matrix is excellent,the composite with the KBM-7803 modified microcapsule content of 6wt%have the highest self-heal efficiency of 77.4%.
