摘　　要：通过将改性的纳米高吸热剂炭黑(CB)添加到对苯二甲酸乙二醇酯(PET)中进行原位聚合反应,得到PET-CB纳米复合材料。采用差热扫描量热法(DSC)、热重分析法(TGA)、热态偏光显微镜(POM)、扫描电镜(SEM)、红外光谱等测试手段对PET-CB纳米复合材料的结构和性能进行了分析和表征。结果表明:纳米材料在复合材料中分散良好;复合材料比纯PET的分解温度提高了1.08°C;PET-CB纳米高吸热材料的吸热性能良好,能有效节约能源。The modified nano-high heat absorption agent carbon black（CB） was added to the polyethylene terephthalate（PET） and the PET-CB nano-composite material was prepared through in situ polymerization.The structure and performance of PET-CB nano-composite material were analyzed and characterized through differential scanning calorimeter（DSC）,thermal weight analysis（TGA）,polarization microscope（POM）,scanning electron microscope（SEM）,infrared spectrometer,etc.Results show that nano-high heat absorption agent carbon black disperses well in PET.The decomposition temperature of PET-CB nano-high heat-absorbing composite material is 1.08 °C higher than that of pure PET.The heat absorbing performance of PET-CB nano-composite material is good,which can save energy effectively.
