The porous anodic alumina was formed by a two-step anodiation in the oxalic acid.ZnO nanoparticles grew in porous alumina templates by sol-gel method depending on the highly ordered nanoporous structure of anodic alumina films.The scanning electron microscopy(SEM) photographs of porous alumina membranes display that the porous alumina templates are parallel-sided hexagonal holes ordering in a scale of a few micrometers.The X energy spectra and the SEM photographs of cleft edge of ZnO/PAA composite systems show that ZnO nano-particles have successfully grown in porous alumina templates.
