제목 Hierarchical Gecko-Inspired Nanohairs with High Aspect Ratio Induced by Nanoyielding
초록 We present a simple method to fabricate the hierarchical polymeric nanohairs with high aspect ratio using multi-branched anodic aluminum oxide (AAO) template and fiber yielding of polystyrene (PS) material. The multi-branched AAO template was prepared by two-step anodization and barrier layer thinning process and the surface of template was modified by silane with hydrophobic nature. The filled hierarchical nanohairs were elongated upon removal of the template due to adhesive force at the modified template and polymer interface. These nanohairs show excellent adhesion and friction property compared to the single-level nanohair and unstructured samples. Furthermore, this nanohairy surface shows remarkable superhydrophobic property similar to natural gecko foot hairs.
