| 摘 要： | 采用悬浮聚合法合成了以正十八烷为囊芯、苯乙烯-新戊二醇二丙烯酸酯共聚物为囊壁的相变材料微/纳胶囊,并通过扫描电子显微镜(SEM)、傅里叶变换红外光谱仪(FT-IR)、差示扫描量热仪(DSC)、热重分析仪(TGA)等对其形貌、结构、热性能、热稳定性等进行了分析。结果表明,相变材料微/纳胶囊形貌完整、分散性好;相变材料微胶囊热稳定良好,其失重起始温度较囊芯材料提高了近40℃;相变材料微/纳胶囊在降温过程中有不同程度的过冷结晶现象。

| Abstract: | Microencapsulated/nanoencapsulated phase change materials (Micro/NanoPCMs) were synthesized through suspension polymerization using styrene-neopentyl glycol diacrylate copolymer (SNGD) as shell and n-octadecane as core, and then the morphology, structure, thermal storage and stability of microcapsules and nanocapsules were investigated by scanning electron microscope (SEM), Fourier transform infrared spectroscopic(FT-IR), differential scanning calorimetry (DSC) and thermogravimetry analysis(TGA).
