文摘	以SiO_2作为载体材料,癸酸-棕榈酸作为相变材料制备癸酸-棕榈酸/SiO_2复合相变材料。基于均匀设计和多元非线性回归法研究了各因素对复合相变材料吸放湿性能和控温性能的影响。结果表明,各因素对性能影响的主次顺序为:溶液pH值>无水乙醇与正硅酸乙酯的物质的量比>癸酸-棕榈酸与正硅酸乙酯的物质的量比>去离子水与正硅酸乙酯的物质的量比>超声波功率;优化制备方案:溶液pH值为3.62,超声波功率为100W,去离子水与正硅酸乙酯的物质的量比为9.67,无水乙醇与正硅酸乙酯的物质的量比为5.21,癸酸-棕榈酸与正硅酸乙酯的物质的量比为0.52。
其他语种文摘	Decanoic-palmitic acid/SiO_2 composite phase change materials were prepared with SiO_2 as carrier material and decanoic-palmitic acid as phase change material. The effect of every factor on moisture absorbing and desorbing performance and temperature control performance of composite phase change materials was studied by uniform design and multivariate nonlinear regression. The results show that primary and secondary sequence of factors affecting performance is solution pH value >mole ratio between absolute alcohol and tetraethyl orthosilicate>mole ratio between decanoic-palmitic acid and tetraethyl orthosilicate>mole ratio between deionized water and tetraethyl orthosilicate >ultrasonic wave power. The optimized preparation plan is solution pH value 3.62,ultrasonic wave power 100W,mole ratio between deionized water and tetraethyl orthosilicate 9.67,mole ratio between absolute alcohol and tetraethyl orthosilicate 5.21,mole ratio between decanoic-palmitic acid and tetraethyl orthosilicate 0.52.
