最近在甲虫鳞片中发现的明亮的白度表明，从有限的样品厚度中可以获得显著的白度、亮度和不透明度。这是通过优化鞘翅鳞片中散射中心的堆积密度来实现的。在这里，我们直接测试和应用这个想法的白度和亮度在生产和纸张上的矿物涂料的外观，通过改变散射中心参数，支持其光学特性。通过仿生设计原理，我们发现，理想的高光学散射从矿物涂层可以实现。在商业上，通过使用适当设计的涂层配方，这导致使用较少散射材料的相等光学性能的前景。
The recent discovery of brilliant whiteness in ultrathin beetle scales indicated the availability of significant whiteness, brightness, and opacity from limited sample thickness. This is achieved in the beetle through optimization of the packing density of scattering centers in its elytral scales. Here, we directly test and apply this idea to whiteness and brightness in the production and appearance of mineral coatings on paper by varying the scattering center parameters that underpin its optical properties. Through biomimetic design principles, we find that desirably high optical scattering from mineral coatings can be achieved. Commercially, by using appropriately designed coating formulations, this leads to the prospect of equal optical performance using less scattering material.
