棕榈醇-棕榈酸-月桂酸/SiO2复合相变调湿材料的制备
Preparation of Hexadecanol-Palmitic Acid-Lauric Acid/SiO2 Composite as Phase Change Material for Humidity Control
以SiO2为载体、以棕榈醇-棕榈酸-月桂酸为相变材料制备了棕榈醇-棕榈酸-月桂酸/SiO2复合相变调湿材料, 用等温吸放湿法、步冷曲线法、红外光谱分析(FT-IR)、扫描电镜(SEM)、激光粒度分析(LPSA)、热重分析(TG)及差示扫描量热分析(DSC)等手段对其进行了表征。结果表明: SiO2对棕榈醇-棕榈酸-月桂酸有较好的包裹效果, 所形成的棕榈醇-棕榈酸-月桂酸/SiO2复合相变调湿材料不但具有较好的控温性能, 还具有良好的调湿性能。
hexadecanol-palmitic acid-lauric acid/SiO2 composite as phase change material for humidity control was prepared with SiO2 as carrier and hexadecanol- palmitic acid- lauric acid as phase change material. The performance, molecular structure and morphology of the prepared composite were characterized by using methods of isothermal sorption, cooling curve, FT-IR, SEM, LPSA, TG, DSC and so on. The results show that SiO2 was good coated with hexadecanol-palmitic acid-lauric acid; the prepared phase change material exhibits good performance both in temperature- and humidity-control.
