    摘要: The embodiments described herein relate to anodizing and anodized films. The methods described can be used to form opaque and white anodized films on a substrate. In some embodiments, the methods involve forming anodized films having branched pore structures. The branched pore structure provides a light scattering medium for incident visible light, imparting an opaque and white appearance to the anodized film. In some embodiments, the methods involve infusing metal complex ions within pores of an anodized. Once within the pores, the metal complex ions undergo a chemical change forming metal oxide particles. The metal oxide particles provide a light scattering medium for incident visible light, imparting an opaque and white appearance to the anodized film. In some embodiments, aspects of the methods for creating irregular or branched pores and methods for infusing metal complex ions within pores are combined.
