摘要

为探讨脱木素对木粉孔结构及对相变材料封装效率的影响及作用关系，以轻木木粉为封装基体，将木粉脱木质素处理后，通过真空浸渍法将聚乙二醇（PEG）封装于木粉中制备了一种复合相变储热材料，通过场发射扫描显微镜（SEM）、比表面积和孔径分析仪（BET）、傅里叶红外光谱测试（FTIR）、差示扫描量热测试（DSC）分析了脱除木质素对其孔径结构及封装效率的影响。结果表明，脱木素后木粉介孔增多，孔结构得到改善，相变材料的封装效率提升至75.1%。熔融温度和潜热分别为53.3 ℃和137.8 J/g，且在热循环实验后表现出良好的热可靠性。

Abstract

In order to investigate the effect of delignification on the pore structure of balsa (,Ochroma pyramidale,) wood flour and the packaging efficiency of phase change materials, a composite phase change heat storage material was prepared by encapsulating polyethylene glycol in delignified balsa wood flour using the vacuum impregnation method. The effects of delignification on the pore structure and packaging efficiency were analyzed by SEM, BET, FTIR and DSC, respectively. The results showed that the mesopores increased and the pore structure improved after delignification. The packaging efficiency of phase change heat storage materials increased to 75.1%. The melting temperature was 53.3 ℃ and the latent heat was 137.8 J/g. The phase change heat storage material showed a good thermal reliability after the thermal cycle experiment.
