| 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. |
