In Mother nature, there are lots of unique structure. Making re-entrant structure is difficult via photolithography, which is one of the semiconductor process. We have studied how to make various shape of re-entrant structures using swelled hydrogel. Swelling the patterned hydrogel and then replicating the replica is easier than conventional patterning method to make unique structure. By adjusting the spacing of the pattern and the ratio of the material, the structure can be controlled. In this work, we present that 3D structures by this process can be applied to oleophobic surfaces. |
