초록 | Colloidal spheres absorbed at liquid-liquid interface can form two dimensional (2D) ordered structures by self-organization as they form 3D colloidal crystals in bulk phase. Recent interest in 2D sphere packing at a spherical interface stems from its relevance to drug delivery, spherical crystallography and materials science. However, sphere packings in 2D arrangement at liquid-liquid interface have not been fully understood relative to 3D sphere packings. Herein, we examined the structural behavior and mobility of Bancroft-type emulsions, which were stabilized by small colloidal particles adsorbed from continuous phase, and developed a simple method for fabricating polymeric particles with complex surface morphologies using a particle-stabilized photo-curable emulsion in aqueous medium. Especially, raspberry-like or golf ball-like particles were produced with controlled surface morphologies by changing colloidal surface chemistry. |
