Orientation control of supramolecular columns by photo-thermal laser heating on graphene light absorbing layer |
| 초록 |
Self-assembling properties of soft materials has been investigated for the formation of highly periodic nanostructures. One of soft materials, supramolecular structures are attractive due to their advantageous properties such as small feature size (2 - 10 nm), various chemical functionalities, and fast stabilization time (~few mins) to self-assembly. In this research, we demonstrate directed self-assembly of supramolecular columns by photo-thermal annealing. Thermal gradient was generated from irradiated laser beam onto photo-thermal conversion layer. Thermal gradient oriented the supramolecular columns, then four different orientations of supramolecular columns were observed by controlling laser power and laser scanning velocity. It was revealed that quench boundary velocity mainly affected to the orientation direction. This method can be applied for supramolecular structures with different phases and dimensions, then various periodic nanostructures can be generated. |
