3D multilevel texturing is of great interest due to wide range of applications including surface science and optics. However, typical fabricating methods are still suffer from a number of factors such as complicated process and low flexibility of structural features. Herein, we suggest a generic route for fabricating 3D multilevel structure by combining solvent-assisted soft imprint and photofluidic motion of an azopolymer (i.e., surface relief gratings (SRGs)). Our method allows one to fabricate a variety of structural motifs with precisely controlled structural features in a very simple manner. Moreover, one of the interesting intrinsic properties of azopolymeric pattern (e.g., SRGs) is that the pattern can be erased (also can be rewritten) by illumination with circularly polarized light, thus this phenomenon provides unprecedented flexibility of pattern shaping. We expect this study could open up new avenues for fabrication of 3D multilevel textured structure. |
