摘　　要：通过一步中和法制备得到丙胺乳酸盐离子液体,再通过机械混合法得到了一系列不同质量配比的丙胺乳酸盐/肉豆蔻酸复合相变储能材料。通过差热分析仪和导热测试仪等手段对丙胺乳酸盐—肉豆蔻酸复合相变材料的熔点、过冷度、潜热和导热系数进行了表征。结果表明,少量丙胺乳酸盐离子液体的加入可以调控相变体系熔点,同时在潜热损失不大的情况下,可以一定程度上提高体系导热系数,为人们提供了一种新的调控有机相变储热材料的方法。The propylamine lactate ionic liquid was prepared via one step neutralization method firstly, then a series of different mass proportion of propylamine lactate/myristic acid composite phase change materials were obtained by mechanical mixing. The melting temperature, degree of super - cooling, latent heat and thermal conductivity of propylamine laetate/myristic acid phase change composite were characterized by DSC and thermal conductivity analyzer. The result showed that adding a small amount of propylamine lactate could adjust the melting temperature of phase change composite. Meanwhile, under the condition of little latent heat loss, the thermal conductivity of the composite could be improved to a certain extent.
