| 논문초록 | One-dimensional nanostructures align under external forces, exhibiting macroscopic anisotropic properties. However, research on aligning chains composed of colloid particles is limited. In addition, conventional polymer chains of monomers can be stretched under external forces. However, the analysis of chain stretching is limited to very high molecular weight polymer chains such as bottle-brush polymers. In this presentation, we demonstrate the alignment and stretching of colloidal chains of diblock copolymer micelles, which can be regarded as a nanoscale analogue of conventional polymers. We directly examined individual chains coated on a substrate with electron microscopy and conducted a quantitative analysis of the orientation and stretching of these chains. Additionally, to demonstrate the aligned colloidal chains as a template for orienting functional materials, we introduced fluorophores into the aligned chains, which were visualized using a confocal fluorescence microscope. |
