The synthesis of bottlebrush polymers with discrete side chains, their surface pressure isotherm measurements, and thin film molecular dynamics simulations are reported. Our results show that monolayers of bottlebrushes with discrete side chains achieve higher packing densities and exhibit previously unknown, distinct phase transitions that are unseen in their disperse counterparts. The combination of experimental findings and simulation results show that shape-defined bottlebrush polymers can advance structure–property relationship studies of branched polymers and the theoretical descriptions of polymer monolayer self-assembly.

阐明侧链分散性对空气-水界面处的瓶刷聚合物组装的影响

报告了具有离散侧链的瓶刷聚合物的合成、它们的表面压力等温线测量和薄膜分子动力学模拟。我们的结果表明，具有离散侧链的单层瓶刷可实现更高的填充密度，并表现出以前未知的、独特的相变，而这些相变在分散的对应物中是看不到的。实验结果和模拟结果相结合，表明形状定义的瓶刷聚合物可以推进支化聚合物的结构-性能关系研究和聚合物单层自组装的理论描述。
