光能触发式变色薄膜是一种新的材料,被运用到各种领域。实验以聚乙烯(PE) 为母料,光变绿荧光粉为变色剂,通过挤出吹塑法来制作成膜。通过对成膜力学性能、光学性能和变色性能的研究得知,当IV区温度为188 ℃,聚乙烯(PE)最佳的熔融温度,光变绿荧光粉与聚乙烯的质量比为1 :100 时,成膜的变色性能最佳,变色灵敏度最高。

Light trigger color changing film is a kind of new functional materials used in various fields. Polyethylene was used as masterbatch and green phosphor as color agent in the experiment. The film was prepared by blow molding. The mechanical properties, optical properties and the color changing properties of the film were tested. The result showed that the best temperature of polyethylene melting is 188 ℃in IVarea; when the ratio of green phosphor and polyethylene is 1%, color changing properties is the best and color changing sensitivity is the highest.
