| 논문초록 | Block copolymer (BCP) particles have garnered significant attention due to their versatility in programmable shapes and intricate nanostructures. In this talk, we introduce photonic particles based on BCP self-assembly with more than 300 axially stacked layers, exploiting the macrophase separation of multiple incompatible components and the microphase separation of BCPs. Our method leads to the formation of Janus colloids, where an oil droplet merges with a nanostructured polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) cone. We highlight the capability to precisely adjust the particle morphology and the corresponding orientation, dispersion, and structural color window by modulating the volume ratio between PS-b-P2VP and silicone oil. We also demonstrate the potential of this study by presenting a multicolor-patterned array of photonic colloids. |
