| 논문초록 | Stratification of a particle mixture is a very interesting process due to the impartment of unique surface properties that are quite different from the interior, which can be utilized in various fields, such as multi-functional coatings and controlled drug-releases. Thus, the related studies have been conducted intensively, and in particular, a self-stratification of particle mixtures have been attracted recently. This self-stratification of particle mixture solutions can be simply formed by evaporating the solvent, but this does not seem to be an appropriate process to achieve a uniformly stratified structures with a large surface area. Therefore, we here introduce a new approach for stratifying the particle mixtures by applying a lateral compression to particle mixture layers at the air-water. Based on this, we successfully report that the uniformly stratified structures are simply achieved with a large area, and the thickness of each particle layer can be even controllable. |
