In this study, we propose a highly ordered honeycomb-patterned film using polymer materials via solution coating system. Honeycomb patterned surface, so-called breath figure, has been studied under the humid flow for superhydrophobic surface, photonic structure, and sensors. However, we produced a honeycomb structures without controlling humidity by mixing non-solvent into polymer solution to induce phase separation as a breath figure. Furthermore, combination of solvent evaporation coating method with adding non-solvent has advantages to fabricate honeycomb-patterned film in a short time, control the shape of patterns, and pattern polymer film on a large area. This approach for patterning can be applied to functional materials for the future technology. |
