光致变色涂料的制备及其性能研究

Prepairation and Study on Performance of the Photochromic Coating

配制了一种螺噁嗪光致变色聚丙烯酸酯涂料。研究了涂料的光致变色性能和抗疲劳性能,结果表明,涂膜在紫外灯照射下由无色变为蓝色,这种变化是可逆的。而且,紫外灯连续照射8小时后,涂膜仍具有良好的可逆光致变色性能,证实了这种光致变色涂料具有较高的抗疲劳性能。

A spirooxazine photochromic poly（ acrylic acid） coating was prepaired, By the investigation of the photochromism and the fatigue resistance of coatings, it was shown that the coating films could change from colorless to blue reader the irradiation of ultraviolet light, and this change was reversible. In addition, after irradiation of ultraviolet light for 8 hours, the coating films still exhibited reversible photochromism. It was conformed that the photochromic coating had excellent fatigue resistance.
