Abstract

Hierarchical porous inorganic materials have attracted much attention, due to their large surface area and fast substance diffusion. We have prepared hierarchical porous films composed of Al₂O₃ nanoparticles (NPs) using the breath figure technique. The Al₂O₃ NPs were stabilized using an amphiphilic copolymer that contained catechol moieties. Porous films of polymer-stabilized Al₂O₃ NPs were prepared using water droplets as templates. The films were sintered to produce hierarchical porous Al₂O₃ films that were thermally and chemically stable.
