选取月桂醇(DD)、棕榈醇(HD)为原料,采用熔融共混法制备了DD-HD二元相变材料,利用步冷曲线法对不同质量配比的混合相变材料进行研究分析。结果表明:当DD和HD质量比为83∶17时,二元相变材料为共晶相变材料,差示扫描量热仪(DSC)测得其融化温度为17.0℃、凝固温度为15.8℃、相变潜热为210.3J/g。傅里叶红外光谱(FT-IR)测试表明两者仅为物理结合。二元共晶相变材料进行了600次冻/融循环实验,400次冻/融循环后相变材料的相变温度变化不超过0.1℃,体系热稳定性良好。
1-dodecanol (DD) and 1-hexadecanol (HD) binary phase change materials prepared by melt blending method using 1-dodecanol and 1-hexadecanol as raw materials.The step-cooling curve method was used to study and analyze the mixed phase change materials with different mass ratios.When the mass ratio of DD and HD was 83∶17,the binary phase change material was eutectic phase change material.The measuring results of differential scanning calorimeter (DSC) showed that the melting temperature,solidification temperature and latent heat of phase change were 17.0℃,15.8℃ and 210.3J/g,respectively.Fourier transform infrared spectroscopy (FT-IR) testing results presented that the two materials were only physically combined.The DD-HD eutectic phase change material underwent 600 melting/freezing cycles,and after 400 melting/freezing cycles,the phase transition temperature of the binary eutectic phase change material did not change more than 0.1℃,demonstrating excellent thermal stability of the system.
