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/蒙脱土复合储能材料。用XRD、IR、SEM、DSC等方法对其结构及储能性能进行了研究。结果表明,复合相变材料具有较适宜的相变温度,较高的相转变焓,较好的热稳定性,储能性能适合做建筑相变材料。The dodecanol/bentonite composite PCM was prepared by a ultrasonic and liquid intercalation method using anhydrous ethanol as a solvent. The structure and properties of the materials were studied by XRD,IR, SEM and DSC. The results showed that composite PCM appropriate phase change temperature, higher latent heat and good thermal stability. These thermal properties make the composite material suitable for building material.
