摘要

摘要: 以Ce-La-TiO₂空心微球作为载体材料，棕榈醇（H）-棕榈酸（PA）-月桂酸（LA）作为相变材料，采用溶胶-凝胶法与真空吸附法制备H-PA-LA@（Ce-La-TiO₂）光-热-湿复合材料，利用UV-Vis、XRD、DSC、DVS和SEM分析技术测试与表征其光响应性能、热性能、湿性能、组成成分和微观形貌。结果表明：H-PA-LA@（Ce-La-TiO₂）光-热-湿复合材料呈现均匀的球体，粒径较小且分散较好，实现Ce离子与La离子协同作用；当Ce（NO₃）₃·6H₂O与La（NO₃）₃·6H₂O的质量比为1∶1时，H-PA-LA@（Ce-La-TiO₂）光-热-湿复合材料具有最优的光响应性能；H-PA-LA与（Ce-La-TiO₂）空心微球的质量比为1∶2时，H-PA-LA@（Ce-La-TiO₂）光-热-湿复合材料具有最优热性能；真空干燥箱的真空度为0.07 MPa时，H-PA-LA@（Ce-La-TiO₂）光-热-湿复合材料具有最优湿性能。

Abstract: The hexadecanol (H)-palmitic acid (PA)-lauric acid (LA)@(Ce-La-TiO₂) photocatalytic-heat-mositure composites were prepared experimentally by the sol-gel method and the vacuum adsorption method, with the Ce-La-TiO₂ hollow microspheres as the carrier material and H-PA-LA as the phase change material separately. The light response property, heat property, mositure property, composition and microstructure were tested and characterized by UV-Vis, XRD, DSC, DVS and SEM, respectively. The results show that the H-PA-LA@(Ce-La-TiO₂) photocatalytic-heat-mositure composites present as uniform spheres, with small particle size and good dispersion, which promotes the coordinated effect of La ions and Ce ions. When the mass ratio of Ce(NO₃)₃·6H₂O to La(NO₃)₃·6H₂O is 1:1, the H-PA-LA@(Ce-La-TiO₂) photocatalytic-heat-mositure composites can obtain the optimal light response property. When the mass ratio of H-PA-LA to Ce-La-TiO₂ hollow microspheres is 1:2, H-PA-LA@(Ce-La-TiO₂) photocatalytic-heat-mositure composites show the best heat property. When the vacuum degree of vacuum drying oven is 0.07 MPa, the H-PA-LA@(Ce-La-TiO₂) photocatalytic-heat-mositure composites show the optimal moisture property.
