【摘要】：为了拓宽有机可逆热致变色材料的变色温度范围,分别以结晶紫内酯为隐色剂,双酚A为显色剂,十四醇和十六醇为溶剂制备热致变色复配物,并通过对复配物变色性能评价分析确定隐色剂、显色剂、溶剂三者间的最佳配比;在此基础上,以十四醇-十六醇二元共晶体系为溶剂,首先通过理论推导预测二元共晶体系的理论最低共熔点,再通过实验确定二元共晶体系的实际最低共熔点,拓宽材料变色温度范围。结果表明:隐色剂、显色剂、溶剂三者间的最佳配比为1∶4∶65;通过色差分析和DSC分析得知,十四醇-十六醇二元共晶体系复配物变色效果较好,变色温度范围为20~43℃。
[Abstract]:In order to widen the temperature range of organic reversible thermochromic materials, the thermochromic compound was prepared by using crystal violet lactone as cryptochromic agent, bisphenol A as chromogenic agent, tetradecanol and hexadecanol as solvent, respectively. Based on the evaluation and analysis of the discoloration performance of the complex, the optimum ratio of the cryptochromic agent, chromogenic agent and solvent was determined, on the basis of which the binary eutectic system of tetradecanol and hexadecanol was used as the solvent. First, the theoretical minimum eutectic point of binary eutectic system is predicted by theoretical derivation, and then the actual minimum eutectic point of binary eutectic system is determined by experiments, and the range of material color change temperature is widened. The results show that the optimum ratio of cryptochromic agent, chromogenic agent and solvent is 1: 4: 65. The results of color difference analysis and DSC analysis show that the color change effect of the binary eutectic system of tetradecanol and hexadecanol is better, and the color changing temperature range is 20 鈩，
