摘　　要：采用双组份熔融复合纺丝工艺,设计出皮层具有光热转换功能,芯层具有相变储能功能的皮芯型光热转换相变聚对苯二甲酸1,3丙二醇酯(PTT)纤维,采用扫描电子显微镜、光学显微镜、傅里叶红外光谱仪、热重分析仪、差示扫描量热测试仪、热红外成像仪等对光热转换相变PTT纤维的结构与性能进行研究。结果表明:光热转换粉体、相变材料均以分散相形式均匀分散在PTT连续相中,光热转换相变PTT纤维的耐热性未受到明显影响。在调温效果测试中,与光热转换PTT纤维相比,芯层相变材料使光热转换相变PTT纤维的升温与降温速率均较慢,但测试完全结束时,光热转换相变PTT纤维的温度分别比PTT纤维、光热转换PTT纤维高0.7℃、1℃,表现出良好的光热转换、相变蓄能性能,具有较好的温度调节功能。The sheath-core composite PTT fibers with function of photo-thermal conversion/phase change respectively were prepared by melting spinning.The property of the composite PTT fibers were characterized by the SEM,optical microscope,FTIR,TG,DSC and thermal imaging camera.The results showed that the photo-thermal converse powders and phase change materials dispersed uniformly in the matrix,and the thermal stability of the fibers maintained after the addition functional materials.For the temperature adjustable property,compared with the pure photo-thermal converse PTT fibers,the existence of phase change components slowed the heating-up and heating-down velocity.Moreover,after the testing,the temperature of photo-thermal converse/phase change composite PTT fibers was higher than that of pure PTT fibers and photo-thermal converse fibers,indicating the good photo-thermal converse,phase change energy store and temperature adjustable properties.
