摘　　要：采用原位聚合法,以密胺树脂为壁材,复合脂肪醇为芯材,成功制备了相变储能微胶囊。粒径测试仪测出其平均粒径为5.253μm;扫描电镜图片显示,制备出的微胶囊分布均匀、结构完整;红外光谱曲线(IR)对比可以看出,芯材已经被壁材密胺树脂包封;微胶囊样品的差热扫描(DSC)测试结果表明,其相变焓为122.5 J/g;热重-热差(TG/DTG)测试结果显示,制备的微胶囊样品在180℃以内性能稳定,可用于储能纺织品的开发。另外,织物热性能测试结果显示,聚酰胺(PA)涂层浆料中添加储能微胶囊后,能提高PA涂层织物的调温性能。Using melamine resin as the wall material and the composite fatty alcohols as the core material, the phase change energy storage microcapsules are successfully prepared by in-situ polymerization method. Particle Size Measurer results indicate that the average diameter of the prepared microcapsules is 5.253 μm. SEM Images results show that the prepared microcapsules have uniform distribution and complete structure. The results from Infrared Spectrum Curve（IR） tests prove that the core materials are encapsulated by melamine resin. DSC tests illustrate that the prepared microcapsules have a phase transition enthalpy of 122.5 J/g. TG/DTG tests reveal that the prepared microcapsule samples can keep stable performance only if the temperature is less than 180 ℃, which suggest that they could be used for the development of energy-storage fabrics. Besides, the results from fabrics thermal perfor- mance test indicate that if the prepared microcapsules are added into the polyamide coating paste, the thermo-regu- lated performance of the polyamide coating paste will be improved.
