【摘要】：為了拓寬有機可逆熱致變色材料的變色溫度范圍,分別以結晶紫內酯為隱色劑,雙酚A為顯色劑,十四醇和十六醇為溶劑制備熱致變色復配物,并通過對復配物變色性能評價分析確定隱色劑、顯色劑、溶劑三者間的最佳配比;在此基礎上,以十四醇-十六醇二元共晶體系為溶劑,首先通過理論推導預測二元共晶體系的理論最低共熔點,再通過實驗確定二元共晶體系的實際最低共熔點,拓寬材料變色溫度范圍。結果表明:隱色劑、顯色劑、溶劑三者間的最佳配比為1∶4∶65;通過色差分析和DSC分析得知,十四醇-十六醇二元共晶體系復配物變色效果較好,變色溫度范圍為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，
