摘要：高度支化的“瓶刷”聚合物是一类以侧链为特征的大分子，所述侧链从通常为线性的主链密集接枝。它们独特且通常令人满意的性质源于侧链之间的空间排斥，这会使分子轮廓变硬并增加链间间距。由于聚合物科学所有分支的协同进步，我们对这些材料的基本理解、实际合成和应用都出现了复兴。从这个角度来看，我们概述了各种各样的新功能瓶刷材料如何从整个材料设计过程的见解的融合中出现;合成，表征，加工和建模的集成已经证明了这些支链大分子作为分子工程通用平台的前景。我们讨论了如何进一步开发这个平台，以展示新的材料性能和平衡，并付诸实践，由于下一代的合成，分析，处理和计算工具在材料化学。
ABSTRACT: Highly branched "bottlebrush" polymers are a class of macromolecules characterized by side chains that are densely grafted from a backbone that is typically linear. Their unique and often-desirable properties stem from steric repulsion between side chains, which stiffens the molecular contour and increases interchain spacing. There has been a renaissance in both our fundamental understanding, practical synthesis, and application of these materials, due to synergistic advances in all branches of polymer science. In this perspective, we outline how a wide variety of new functional bottlebrush materials have emerged from the convergence of insights from the entire materials design process; the integration of synthesis, characterization, processing, and modeling has demonstrated the promise of these branched macromolecules as a versatile platform for molecular engineering. We discuss how this platform may be further developed to exhibit novel material properties in and out of equilibrium and put into practice due to the next generation of synthetic, analytical, processing, and computational tools in materials chemistry.
