摘要:

以SiO₂为载体材料、以脂肪酸为相变材料、以无水酒精和去离子水为溶剂, 用溶胶-凝胶法制备脂肪酸/SiO₂复合相变材料, 用SEM、LPSA、FT-IR、DSC等手段对其表征, 研究了芯材种类、相变材料用量、无水酒精用量、去离子水用量、溶液pH值、超声波功率等因素对脂肪酸/SiO₂复合相变材料织构的影响。结果表明, 脂肪酸/SiO₂复合相变材料织构受到芯材种类、相变材料用量、无水酒精用量和去离子水用量的影响较大, 也与溶液pH值和超声波功率有关。其最佳工艺参数为: 癸酸-棕榈酸为芯材、癸酸-棕榈酸与正硅酸乙酯的物质的量比为0.4、无水酒精与正硅酸乙酯的物质的量比为5、去离子水与正硅酸乙酯的物质的量比为9、溶液pH值4和超声波功率为200 W。

Abstract：

The phase change materials of fatty acid/SiO₂ composite were prepared by sol-gel method with SiO₂ as carrier material, fatty acid as phase change material, absolute alcohol and deionized water as solvent, Which then were characterized by scanning electron microscope (SEM), laser particle size analyzer (LPSA), Fourier transform infrared (FT-IR), differential scanning calorimetry (DSC) etc. The effect of the type of cores, the amount of phase change material and absolute alcohol and deionized water as well as the solution pH value and ultrasonic wave power on the texture of the prepared composites were investigated systematically. The results show that the texture of the phase change materials of fatty acid/SiO₂ composite was greatly influenced by the type of cores, the amount of phase change material and absolute alcohol and deionized water, and also related to solution pH value and ultrasonic wave power. The optimal processing parameters for preparation a good composite are: decanoic acid-palmitic acid acts as core, the mole ratio of decanoic acid-palmitic acid to tetraethyl orthosilicate is 0.4, the mole ratio of absolute alcohol to tetraethyl orthosilicate is 5, the mole ratio of deionized water to tetraethyl orthosilicate is 9, solution pH value is 4 and ultrasonic wave power is 200 W.
