热能触发式变色薄膜是一种新的功能型材料,可以用于各个领域。 在前人研究的基础上,对热能触发式变色薄膜进行了研制以及性能研究,以高分子树脂 PVA 为母液,在研制过程中加入甘油、甲基纤维素、吐温 80、变色剂和氯化铵。 研究发现,当吐温 80 体积分数为 0. 2% ,甘油体积分数为 0. 9% ,甲基纤维素质量分数为0. 25% ,变色剂质量分数为 1% ,氯化铵质量分数为 0. 14% 时,效果最优,热能触发式变色薄膜的各种性能最好。

Heat triggered color changing film is a kind of new functional materials, which can be used in various fields. On the basis of previous studies, heat triggered color changing film was prepared and its performance was studied. PVA was used as mother liquor, and glycerin, methyl cellulose, twain 80, color agent, and ammonium chloride was added to prepare the film. The result showed that when twain 80 0. 2% , glycerol 0. 9% , methyl cellulose 0. 25% , color agent 1% , ammonium chloride 0. 14% , the prepared heat triggered color changing film has the best overall performance.
