摘要

摘要: 以硅烷偶联剂改性SiO₂为壁材，癸酸（DA）-棕榈酸（PA）为芯材，利用超声波辅助溶胶-凝胶法制备DA-PA@改性SiO₂调温调湿复合材料，分析了硅烷偶联剂用量、超声波功率、超声波时间和超声波温度对DA-PA@改性SiO₂调温调湿复合材料粒径的影响，以及相关性能。结果表明，利用超声波辅助溶胶-凝胶法制备DA-PA@改性SiO₂调温调湿复合材料，可以显著降低粒径尺寸和减小粒径分布。当硅烷偶联剂用量为4.0 g、超声波功率为120 W、超声波时间为100 min和超声波温度为60℃时，DA-PA@改性SiO₂调温调湿复合材料的粒径较小且粒径分布较窄，即d₉₀=87.36 nm、d₅₀=63.34 nm、d₁₀=44.02 nm和d₉₀-d₁₀=43.34 nm，在相对湿度40.0%~65.0%范围内的平衡含湿量为0.1864~0.2379 g/g，相变温度为20.23~23.59℃，相变潜热为40.91~46.72 J/g，稳定性能良好。

Abstract: With silane coupling agent modified SiO₂ as wall material and decanoic acid (DA)-palmitic acid (PA) as call material, the DA-PA@modified SiO₂ temperature and humidity control composites were prepared by sol-gel method with ultrasonic wave-assisted. The effects of the content of silane coupling agent, ultrasonic wave power, ultrasonic wave time and ultrasonic wave temperature on the particle size of the DA-PA@modified SiO₂ temperature and humidity control composites and related properties were investigated. The results show that the particle size and its distribution of the DA-PA@modified SiO₂ temperature and humidity control composites can be significantly reduced using sol-gel method with ultrasonic wave-assisted. With the content of silane coupling agent of 4.0 g, ultrasonic wave power of 120 W, ultrasonic wave time of 100 min and ultrasonic wave temperature of 60℃, the DA-PA@modified SiO₂ temperature and humidity control composites has small diameter and narrow particle size distribution, such as d₉₀=87.36 nm, d₅₀=63.34 nm, d₁₀=44.02 nm and d₉₀-d₁₀=43.34 nm. Its equilibrium moisture content in the relative humidity of 40.0%-65.0% is 0.1864-0.2379 g/g, phase change temperature is 20.23-23.59℃, phase change latent heat is 40.91-46.72 J/g, and the stability performance is good.
