摘要: 通过溶剂蒸发法制备了聚砜包覆液体石蜡的微胶囊,通过扫描电子显微镜、傅里叶红外光谱仪、热重分析仪、纳米压痕测试仪对微胶囊的表面形貌、化学结构、热性能、壳层硬度进行表征。结果表明,使用聚乙烯醇和十二烷基硫酸钠作为乳化剂,反应温度为35 ℃时,制备的微胶囊球形规整、表面光滑,平均粒径约15 μm,微胶囊具有较好的热稳定性和力学性能。

Abstract: The microcapsules composed of a liquid paraffin core and polysulfone (PSF) shell were prepared by a solvent evaporation method. The morphology, chemical structure, thermal properties and shell hardness of the microcapsules were investigated by scanning electron microscopy, Fouriertransform infrared spectrometry, thermogravimetric analysis and nanoindentation. The results indicated that the microcapsules exhibited a smooth surface with a mean particle size of about 15 μm when being synthesized at 35 ℃ by using poly(vinyl alcohol) and sodium dodecyl sulfate as emulsifiers. The microcapsules also achieved a high thermal stability and good mechanical properties.
