摘要
采用溶胶-凝胶法制备了SiO2作为载体的脂肪酸复合有机相变材料,脂肪酸在SiO2网络空间内发生相变,在宏观上始终呈现固体粉末状。采用差示扫描量热方法、热重和红外光谱对样品进行了热力学、微相结构分析。实验结果显示出了明显的储放热行为。
Fatty acid/SiO2 composite phase change materials were prepared by sol-gel method. Fatty acid changed phase from solid to liquid at inner of SiO2 gel network, and appearance of composite material was solid always. It's thermal properties and microstrueture were studied by DSC and TG and IR. The obtained experimental results showed obvious phase change energy-storing behavior.
