为了解决单一相变材料相变温度过高,不适宜开发智能调温面料的问题,将两种不同规格的聚乙二醇(PEG)进行复合,采用差示扫描量热仪测试其相变温度和相变焓,并使用OriginPro 9.0软件拟合出复合相变材料的不同比例与相变温度和相变焓的模拟曲线和函数关系,采用多目标优化方法建立统一的目标函数,利用lingo11软件确定出适宜开发智能调温面料的复合相变材料。结果表明:摩尔分数比为1∶9的试剂PEG-800与药用PEG-1000的复合相变材料,是最适宜开发智能调温面料的复合相变材料。
In order to solve the problem that the phase transition temperature of a single phase change material is too high, it is not suitable to develop a smart temperature control fabric. Two kinds of polyethylene glycol (PEG) of different specifications are combined and the phase transition temperature is measured by a differential scanning calorimeter And the enthalpy of phase transition. The simulation curve and the function of phase transition temperature and phase transition enthalpy were fitted by using OriginPro 9.0 software. The multi-objective optimization method was used to establish a unified objective function. The software was used to determine Suitable for the development of intelligent thermostat fabric composite phase change material. The results showed that the composite phase change material of PEG-800 and PEG-1000 with molar ratio of 1: 9 is the most suitable composite phase change material for the development of intelligent temperature-control fabrics.
