摘　　要：利用示差扫描量热法(DSC)对甲酚红 -碱土金属离子 -十六醇复配物的可逆热变色过程进行了研究 ,探讨了复配物在加热、冷却过程中发生的各种相变 ,分析了溶剂含量和金属离子含量不同对材料的变色温度、热焓、变色敏锐性等热变色性的影响。The reversible thermochromic process of cresol redalkali earth metal ions_hexadecanol system was studied by differential scanning calorimetry. The phase changes of the composite material during heating and cooling operations were investigated.The effects of concentrations of solvent and metal ions on thermochromic temperature,heat enthalph and thermochromic sensitivity of composite material are discussed. The experimental results provide a theoretical foundation for the selection of optimal ratios of the composite materials.
