复合低温热敏变色储能材料的研制

Preparation of low temperature thermochromatic and energy-storage composite materials

分别以结晶紫内酯为发色体,以双酚A为显色剂,以具有储能作用的高级脂肪醇(CR-2)为溶剂,制备出低温热敏变色储能材料。通过实验对比发色体、显色剂及溶剂不同比例时储能材料的热敏变色性能,确定出发色体、显色体、溶剂的最佳搭配比例。依据施罗德理论对二元储能材料(CR-2、CR-3)进行复合,并按同样比例取代CR-2作为变色材料的介质,从而拓宽了可逆低温热敏变色材料变色温度的范围。结果表明:发色体、显色剂与溶剂的最佳质量比为1∶2.5∶40;通过DSC分析可知,复合后的变色材料同时也是一种优良的储能材料。

This paper synthesized a low temperature thermochromatic and energy-storage material from higher fatty alcohol（CR-2） with crystal violet lactone as chromophore and bisphenol as developer.By contrast of the performances of different ratios of chromophore / developer /solvent,the optimal mixing ratio was determined.According to Schroeder′s theory,the binary energy-storage materials（CR-2 and CR-3）was blended and the same proportion of the blended material was taken to replace CR-2 as the medium of thermochromatic material,thus widening the temperature range of reversible low temperature thermochromatic materials.Experimental results showed that the optimal mass mixing ratio of chromophore / developer/solvent was 1∶2.5∶40,and DSC analysis showed that composite thermochromatic material was also a kind of fine energy-storage material.
