Self‐Oxidation Resistance of the Curved Surface of Achromatic Copper (Adv. Mater. 42/2023)

Achromatic Copper Films Diverse colors can be attained solely through manipulation of the surface of copper. Uniformly oxidizing the copper surface and controlling the thickness of the resulting oxide layer has proven that comprehensive natural coloration can be achieved. In article number 2210564,...

Description
Summary:Achromatic Copper Films Diverse colors can be attained solely through manipulation of the surface of copper. Uniformly oxidizing the copper surface and controlling the thickness of the resulting oxide layer has proven that comprehensive natural coloration can be achieved. In article number 2210564, Young‐Min Kim, Se‐Young Jeong, and co‐workers fabricate a rough copper surface, characterized by dendrites, to realize an extensive spectrum of achromatic colors. This unique rough copper surface, resembling nanocavities, effectively captures and traps light.
