Research Abstract

A colloidal crystal is an ordered array of monodisperse colloidal particles with diameters ranging from a few tens nano to a few micrometer size. Structural and physical character changes are strongly affected by various parameters such as nature of colloidal particles (e.g. chemical structure, diameter), and direction and strength of tensile stress. It is crucial to predict structural and physical character changes of the colloidal crystal induced by external tensile stress using the data from theoretical analysis. In this study, effects of external tensile on morphology of particles and structure of colloidal crystal have been clarified from both experimental and theoretical aspects.
