中文摘要：
以正十八烷为相变材料,凹凸棒土为支撑基体,通过真空浸渍法将相变材料有效地吸附固定于凹凸棒土的孔道结构中,制备出结构稳定、热性能稳定的新型正十八烷/凹凸棒土复合相变储能材料.由凹凸棒土N2吸附试验和SEM图片可以发现凹凸棒土疏松多孔、比表面积大,从而能有效吸附正十八烷相变材料.对制备的新型复合相变储能材料进行DSC测试,并进一步对其进行20次DSC冷热循环测试,样品的相变温度及相变潜热基本保持不变,说明其具有优异的相变蓄热特性和热循环稳定性,具有较好的应用前景.
英文摘要：
N-octadecane/attapulgite composite phase change materials （PCMs） were prepared through vacuum infiltration method by using n-octadecane as phase change materials, attapulgite as supporting materials. N2 adsorp- tion desorption isotherms and scanning electron microscope （SEM） images indicate that attapulgite possesses large specific surface area which can effectively absorb n-octadecane into its multiporous structure. The differential scanning analysis （DSC） curves show that the obtained samples have good thermal properties, and their phase change tempera- ture and latent heat can keep constant after 20 times of thermal testing. The results indicate that the prepared compo- site phase change materials possess excellent thermal stability and have a broad application prospect.
