PREPARATION METHOD OF COLLOIDAL CLUSTERS FROM EMULSIONS USING DROPLETS COMPRISING BINARY OR BI-DISPERSE COLLOIDAL DISPERSIONS

摘要

A noble preparation method of high functional nonspherical colloidal particles is provided, wherein the nonspherical colloidal particles can be applied as a base material of optoelectronic devices since the nonspherical colloidal particles have a regular and unique structure instead of a spherical structure and have two different physical properties in one self-assembled structure. A preparation method of a high functional nonspherical colloidal self-assembly comprises mixing a mixed solution of first colloidal particles and second colloidal particles smaller than the first colloidal particles with a continuous phase liquid; applying a shear stress to a mixture to obtain a droplet; and removing a solvent from the droplet to form a colloidal self-assembly. A preparation method of a high functional nonspherical porous structure comprises the steps of: mixing a mixed solution comprising first colloidal particles and second colloidal particles smaller than the first colloidal particles with a continuous phase liquid, applying a shear stress to a mixture to obtain a droplet, and removing a solvent from the droplet to prepare a high functional nonspherical colloidal self-assembly; and removing the first colloidal particles from the high functional nonspherical colloidal self-assembly.
