Mesoscale honeycomb films for templating inorganic nanomaterials and microspheres

摘要

Mesoscopic structures are important for photonics applications. Here we describe the preparation of honeycomb films with pore diameters of 3 to 7 μm from a crosslinkable polymer by the breath-figure technique, which involves the evaporation of a solution of the solute at high humidity. The honeycomb films then were used as templates for less-then-dense packing of microspheres or for the adsorption of nanocrystalline inorganic oxides. Application of the strongly light scattering and highly porous honeycomb films are in the field of photocatalysis.
