Fabrication of flexible colloidal cluster using depletion interaction |
| 초록 |
Colloidal cluster which has anisotropic feature can be a building block of photonic crystal which has a large photonic band-gap. Various fabrication methods have been tried, however so far, it is not easy to achieve mass production of colloidal cluster. Especially, colloidal cluster with structural flexibility has in a scale of visible range provides great opportunity for understanding of inter-particle interaction of colloidal clusters. Depletion interaction is inter-particle interaction of colloids in polymer-concentrated solution which motivates self-assembly of colloidal particles. In this study, using depletion interaction between anisotropic colloid particle called Pacman particle and simple sphere particle with guided self-assembly and electric field. we suggest a method for fabrication of flexible colloidal cluster with great productivity. |
