Abstract
Galvanostatic anodization in H2SO4 solutions at high current density has been used to prepare porous anodic aluminum oxide (AAO) films for coloring using a non-electrolytic dyeing process. The effects of anodizing current, electrolyte concentration and time on the film morphology have been systematically investigated and compared with previous results. Trends in the film morphology suggest that the pore structure continues to evolve during anodization at high current density, and the film dissolution rate plays a prominent role in the development of the pore morphology. Coloring of the porous films shows that efficacy of non-electrolytic dyeing is dependent upon the porosity of the film and on the state of agglomeration of the suspension of dye particles. ฉ 2019 Elsevier B.V.
