德国一家公司生产了一种五光十色的发光塑料，它是在塑料中加入一种与塑料基质相溶性很好的低分子聚合物染料制成的，该染料中的微细粒子能吸收周围的光，并能发出波长较长的可见光。这种发光塑料可应用在需要高度显示的产品上，例如信号器材、闪光首饰、玩具、商品广告、路标? A German company produces a colorful light-emitting plastic made by adding a low-molecular-weight polymer dye that has good compatibility with a plastic matrix. The fine particles in the dye absorb the surrounding light. Can send a longer wavelength of visible light. This luminescent plastic can be applied to products that require a high degree of display, such as signal equipment, flash jewelry, toys, product advertising, road signs?
