人们希望制造具有不褪色性能和环境友好的彩色涂层。在这项研究中，提出了一种新的方法，从单分散二氧化硅颗粒的结构彩色涂层。结构色涂层膜由二氧化硅颗粒阵列和少量黑色添加剂形成，通过简单的电泳沉积（EPD）技术容易地制备。通过改变施加的电压和沉积时间来控制颗粒阵列的排列。结构色的彩虹色，即角度依赖性，随着粒子阵列的排列而显著变化。通过改变颗粒的大小，可以生产出各种颜色的涂层。EPD法还可以在曲面和复杂形状的材料上获得结构彩色涂层。
It is desirable to fabricate colorful coatings that have nonfading properties and are environmentally friendly. In this study, a novel approach for creating structural color coatings from monodisperse silica particles is presented. The structural color coating films, formed from an array of silica particles with a small amount of black additive, are easily prepared by a simple electrophoretic deposition (EPD) technique. The arrangement of the particle array is controlled by varying the applied voltage and deposition time. The iridescence, that is, the angular dependence, of the structural color dramatically changes with the arrangement of the particle array. A variety of colored coatings can be produced by changing the size of the particles. Structural color coatings on materials with curved surfaces and complicated shapes are also achieved by the EPD method.
