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。
針對熱塑性材料的自脩複,以尿素、三聚氰胺、甲醛共聚物為囊壁,苯乙烯為囊芯閤成瞭包覆苯乙烯的改性脲醛樹脂微膠囊,併採用紅外光譜、掃描電子顯微鏡、納米粒度電位儀等分析瞭微膠囊的化學成分及錶麵形貌,髮現其錶麵粗糙緻密,形狀基本呈毬形,粒徑分佈較集中,包封率為72%,有望應用于自脩複材料。

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.
