Iridescent colloidal crystal coatings with variable structural colors were fabricated by incorporating carbon black nanoparticles (CB-NPs) into the voids of polystyrene (PS) colloidal crystals. The structural color of the colloid crystal coatings was not only greatly enhanced after the composition but also varied with observation angles. By changing the diameter of monodisperse PS colloids in the composites, colloidal crystal coatings with three primary colors for additive or subtractive combination were obtained. After incorporation of the PS/CB-NPs hybrid coatings into polydimethylsiloxane (PDMS) matrix, manmade opal jewelry with variable iridescent colors was made facilely.
通过将炭黑纳米颗粒（CB-NPs）掺入聚苯乙烯（PS）胶体晶体的空隙中，制备了具有可变结构颜色的彩虹色胶体晶体涂层。胶体晶体涂层的结构颜色不仅在复合后得到了极大增强，而且随观察角度而变化。通过改变复合材料中单分散PS胶体的直径，获得了用于加色或减色组合的具有三种原色的胶体晶体涂层。将PS/CB-NPs混合涂层掺入聚二甲基硅氧烷（PDMS）基质后，轻松制作出了具有可变彩虹色的人造蛋白石珠宝。
