| Abstract: |
| 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. |
