Carbon Dioxide Sensing Color Changeable Dyes For Indicating Exposure, Methods of Making and Using Such Dyes, and Apparatuses Incorporating Such Dye |
摘要 |
According to embodiments of the present application, a carbon dioxide sensing color changeable dye can comprise a carbon dioxide status indicator, a solvent, a polymer wherein the carbon dioxide status indicator is dispersed, an optional plasticizer, and an optional agent to facilitate mixing. The color changeable dye is a first color in the presence of a carbon dioxide rich environment and is capable of changing to a second color upon exposure to atmospheric condition for a period of time corresponding to the intended use time of a restricted, disposable or limited use product. Methods of making and using the color changeable dye and apparatuses incorporating such dye are also disclosed. |
