| 논문초록 | Supraparticles have been synthesized by solution process which is difficult to control shapes, sizes and materials. Even though supraparticles have great functionalities and potentials, this limited shape, size and material have been serious huddles of supraparticle researches. Recently we have developed a strategy to synthesize spherical supraparticles on superamphiphobic surfaces with various sizes and components. Due to the strong liquid repellency of superamphiphobic surface, spherical supraparticles could be formed by drying of nanoparticle dispersion with constant contact angle. During the process, no energy consumption and wasting chemicals were applied. By applying magnetic colloids and tuning dispersity of the drop, shapes and porosities of the supraparticles can be controlled. In addition, drying dispersion drop by using Ouzo effect is introduced that allows supraparticle synthesis on normal flat hydrophobic surface by self-lubricating colloidal dispersion evaporation. |
