新型热敏变色储能材料的性能评价

采用传统的涂层工艺，选取水性聚氨酯涂层剂将自制的热敏变色储能材料整理到织物上。对焙烘温度、焙烘时间、涂覆量等主要工艺参数进行研究，当焙烘温度为140°C，焙烘时间为3 min，涂覆量为50 g/m时，经热敏变色储能材料涂层整理后的织物变色性能和储能性能较好。扫描电镜结果显示，热敏变色储能微胶囊在织物上能够很好的黏附固着，保证了整理织物性能的耐久性。涂层整理后织物的DSC测试结果显示，涂层织物的储能性能良好，其起始相变温度为32.5°C，潜热值达到7.388J/g，调热值达到1137.752J/m²。

Performance evaluation of novel thermo color-change and energy-storage materials

The self-made thermo color-change and energy-storage materials were finished onto the fabric with waterborne polyurethane(PU) by conventional coating method. The main processing conditions such as curing temperature, curing time and coating weighy were studied. When the curing temperature was140°C, curing time was 3 min and coating weight was50 g/m, the good discoloration performance and nice energy-storage property of the fabric treated with thermo color-change and energy-storage materials were obtained. Images of scanning electron microscopy (SEM) tests showed the thermo color-change and energy-storage materials were fixed firmly on the fabric, which ensured the durability of the performance of treated fabric. The DSC test of the treated fabric demonstrated obvious thermoregulatory performance, withthe initial phase change temperature32.5°C, enthalpy up to7.388J/g, and thermoregulatory value up to1137.752J/m².
