| 摘 要： | 针对热塑性材料的自修复,以尿素、三聚氰胺、甲醛共聚物为囊壁,苯乙烯为囊芯合成了包覆苯乙烯的改性脲醛树脂微胶囊,并采用红外光谱、扫描电子显微镜、纳米粒度电位仪等分析了微胶囊的化学成分及表面形貌,发现其表面粗糙致密,形状基本呈球形,粒径分布较集中,包封率为72%,有望应用于自修复材料。

| Abstract: | Microcapsules containing styrene were synthesized in an oil-in-water emulsion with poly(urea melamine and formaldehyde resin) as the shell material and styrene as the core substance for self-healing thermoplastic materials.The chemical composition,the shape and surface morphology of microcapsule were analyzed by infrared spectroscopy(IR),scanning electron microscopy(SEM) and nano-particle size analyzer,respectively.The surface was found to be dense and rough.Studies showed that the shape of microcapsules was spherical and its size distribution was concentrated and the core content was 72%.It may be used in self-healing materials. |

| Keywords: | composite resin styrene self-healing microcapsules |
