摘要
A highly ordered open pore honeycomb-structured hybrid film was fabricated by controlling substrate roughness and wettability with the breath figure (BF) method. This composite consists of a porous hydrophobic polyimide (PI) film and a hydrophilic anodic aluminum oxide (AAO) film. The difference between hydrophilic-hydrophobic surfaces yielded an attractive directional water-penetration function. These findings may lead to new applications for honeycomb-structured composites with directional water functionality in fields such as directional drug delivery, biosensors and molecular filtration.
