| Outline of Final Research Achievements |
Novel liquid crystalline gold nano-particles and silica nano-particles have been synthesized in this study. The structures of liquid crystalline ligands used here were a side-on type and a side-end one. The phase transition behavior of these compounds has been studied by a differential scanning calorimetry and a polarizing optical microscope observation. The miscibility of the surface modified inorganic nano-particles with the low molar mass liquid crystal, 5CB, has been also studied. Furthermore, the ER effect of the surface modified gold nano-particles dispersed in 5CB was measured. The characteristics of a dispersed type ER fluid was observed for the composite of the side-on type surface modified gold nano-particles with 5CB in addition to the characteristics of a homogeneous ER fluid.
