Abstract
Special nanostructures of porous anodic alumina (PAA), such as the petal-like micropattern and nanofibers of alumina, cannot be explained by the classical field-assisted dissolution and dynamic equilibrium models. Here, by combination of oxygen bubble mould and plastic flow model, a reasonable explanation for these special nanostructures is proposed. The petal-like micropatterns of PAA and nanofibers of alumina are all clarified by the oxygen bubble mould and the plastic flow model. The self-ordering nanochannels of PAA are attributed to the oxide plastic flow around a gas bubble mould at each pore bottom. The petal-like micropatterns and nanofibers of alumina are attributed to chemical corrosion enhanced by the micro-gas-flow and micro-liquid-flow.
