摘　　要：采用超声震动和液相插层相结合的方法制备出十二醇/膨润土复合储能材料。200次冷热循环测试实验结果表明,其具有较好的热稳定性。复合储能材料与石膏粉有较好的相容性,可制作成相变储能石膏板。与普通石膏板相比,复合石膏板具有较好的保温隔热性能,在建筑中应用具有降低能耗,减缓室内温度波动的功能。The dodecanol/bentonite composite PCM was prepared by a ultrasonic and liquid intercalation method using anhydrous ethanol as solvent. 200 times heating-cooling cycles test showed that the composite PCM had good performance stability. The composite PCM had a good compatibility with gypsum powders, and used in building, the composite gypsum boards as prepared had good energy-storing performance, functions of cutting down energy consumption by decreasing the frequency of internal air temperature swings.
