To date, end-to-end orientation of nanorods has been known perturbed an equilibrium state due to parallel-directional van der Waals and dipole-dipole force. However, in our work, the nanorod assembly configuration can be freely determined by what interaction forces participate dominantly. For end-to-end attraction, capillary force is newly introduced by capturing the nanorods at the air/liquid interface. Interfacial deformation at their tips moves them in the end-to-end direction to reduce total interfacial energy. The assembled superstructures are homogeneously distributed and highly ordered in large-length-scale without 3-dimensional aggregation or coffee ring, which have often been barrier factors in the most film devices. Our method will enable diverse materials with anisotropic characteristics to be assembled into noble and complex 2-D superstructures at large-scale. |
