[PC-12] Characteristics and possibilities of structural color
Experimantal study on usability of artificial opal paintings on various materials
Keywords:Pigment, Color, SDGs
This study concerns structural color using a novel pigment referred to as “artificial opal”. The artificial opal produces color originated in interference with visible light from its periodic microstructure, just as colorful soap bubbles are made from colorless liquids. The artificial opal is composed of oxygen and silicon, the two most abundant elements in Earth’s crust. Here this study reports on the practical use of the artificial opal for painting on tile, anodized aluminum plate, and paper.
