摘要

嵌段共聚物可以自组装成具有各种形态的纳米级物体，为各种应用领域提供定制纳米材料。然而，通过溶液中的自组装实现非晶二维形态仍然具有挑战性。在这里，我们系统地研究了棒（瓶刷）-线圈（线性）嵌段共聚物通过独立改变侧链和主链长度自组装成纳米级圆盘的结构要求。通过在水中的直接自组装，我们确定了最佳聚合物尺寸，可以产生直径为50-200纳米的明确纳米圆盘。

Self-Assembly of Bottlebrush-Linear, Rod–Coil Copolymers into Discoidal Nanoparticles

Block copolymers can self-assemble into nanoscale objects with various morphologies, offering custom nanomaterials for diverse fields of application. However, achieving an amorphous 2D morphology through self-assembly in solution remains challenging. Here, we systematically investigate the structural requirements of rod (bottlebrush)–coil (linear) block copolymers for self-assembly into nanoscale discs by independently varying side chain and backbone lengths. We identify optimal polymer dimensions that yield well-defined nanodiscs with 50–200 nm diameters through direct self-assembly in water.

期刊介绍： ACS Macro Letters publishes research in all areas of contemporary soft matter science in which macromolecules play a key role, including nanotechnology, self-assembly, supramolecular chemistry, biomaterials, energy generation and storage, and renewable/sustainable materials. Submissions to ACS Macro Letters should justify clearly the rapid disclosure of the key elements of the study. The scope of the journal includes high-impact research of broad interest in all areas of polymer science and engineering, including cross-disciplinary research that interfaces with polymer science. With the launch of ACS Macro Letters, all Communications that were formerly published in Macromolecules and Biomacromolecules will be published as Letters in ACS Macro Letters.
