Abstract
Laurate-intercalated films of ZnAl layered double hydroxide (ZnAl-LDH–laurate) were fabricated by anion exchange of laurate with ZnAl-LDH–NO3− films on a porous anodic alumina/aluminum (PAO/Al) substrate. The presence of both microscale and nanoscale hierarchical structures (see SEM image) makes the film superhydrophobic, and thus it has much better corrosion resistance than anodic PAO film alone or ZnAl-LDH–NO3− films.
