A Structure Model for Porous Anodic Alumna Films Formed in Sulfuric Acid

We observed a dear cellular interface network structure in the porous anodic almina films, which were carried out post open-circuit-dissolution in 10% H₃PO₄ solution at room temperature. This new occurred phenomenon cannot be thoroughly interpreted in tears of previous continuous media model leading by field-assistal dissolution formation mechanism.We proposed a novel strcture model to illustrate the porous anodic alumina films structure on assmption that there originally exists a cellular interface structrue in as-formed films.
