The diameter distribution,the thermal stability,the enthalpies and the structure of the microcapsules were analysed by the laser particle size analyzer,X-ray diffractometer,DSC and FT-IR,respectively.

• 采用直接原位聚合法制备了以石蜡为囊芯的脲醛树脂微胶囊,并利用激光粒径分布仪、X射线衍射仪、差示扫描量热仪(DSC)和傅立叶转换红外光谱仪分别分析了微胶囊的粒径分布、热稳定性、热焓值和壳结构。
