| 摘 要： | 以石蜡为相变材料、SiO2介孔分子筛MCM-41为载体,采用溶液浸渍法制备了石蜡/MCM-41复合相变储能材料。应用SEM与TEM测试了复合材料的微观结构,利用TG-DSC测定了复合材料的相变温度、相变潜热及相变可逆性,通过FTIR对复合材料的兼容性进行了表征。实验表明,复合材料表面孔结构改善了相变可逆性,复合相变储能材料中石蜡的适宜质量分数为40%,相变温度为66.6℃,相变潜热为135.3 J/g。石蜡与MCM-41间是简单的嵌合关系,复合材料具有良好的热稳定性和兼容性。 |

| Abstract: | With paraffin as phase change material,MCM-41 mesoporous silica materials as carrier,the paraffin/MCM-41 composite phase change thermal energy storage materials were synthesized successfully via solution immersion.The morphology was observed by means of scan electron microscopy(SEM),transmission electron microscopy(TEM) images,which clearly revealed the structures of molecular sieves and paraffin/MCM-41.The synthesized materials were characterized by means of thermal gravimetry/differential scanning calorim... |
| Keywords: | Phase change material Solution immersion Paraffin Mesoporous molecular sieves |
