The formation of colloids with anisotropically patterned surfaces is of growing interest for the creation of hierarchical structures and the templating of nanoparticles. We have recently shown that well-defined two-dimensional platelets with low areal dispersities can be formed by the seeded growth of a blend of homopolymers and block copolymers. Herein we form rectangular platelets containing two block copolymers with different coronal chemistries. On addition of a solvent that is only able to solvate the corona of one block, we were able to form colloidally stable micelles with patterned surfaces via coronal collapse. Scanning transmission electron microscopy-energy-dispersive X-ray spectroscopy and atomic force microscopy were employed to provide information on the structure and size of the patches decorating the micelle surfaces.

通过冠状链折叠的均匀二维血小板块Comicelles的表面图案化

具有各向异性图案表面的胶体的形成对于分层结构的创建和纳米粒子的模板越来越感兴趣。我们最近表明，通过均聚物和嵌段共聚物的共混物的晶种生长，可以形成具有低面积分散性的明确二维薄片。在这里，我们形成了包含两种具有不同冠状化学性质的嵌段共聚物的矩形片晶。在添加只能溶剂化一个块的电晕的溶剂后，我们能够通过冠状塌陷形成具有图案表面的胶体稳定胶束。使用扫描透射电子显微镜-能量色散 X 射线光谱和原子力显微镜来提供有关装饰胶束表面的贴片的结构和大小的信息。
