单聚合物动力学为研究材料中的分子级相互作用和动态微观结构提供了一种强大的方法。单聚合物链的直接可视化揭示了有关大分子流变学和非平衡动力学的新想法，包括分子个体主义、动态异质性和分子亚群在控制宏观行为中的重要性。近年来，单聚合物动力学领域已扩展到新材料，包括结构复杂的聚合物，如梳子、瓶刷和环状聚合物以及长链聚合物在流动中的缠结溶液。单分子可视化，辅以布朗动力学和蒙特卡罗方法等建模和模拟技术，可以无与伦比地了解聚合物材料的分子尺度动力学。在这篇综述中，通过强调单聚合物动力学领域的重大发展和新物理学的最新进展进行了审查......
Single polymer dynamics offers a powerful approach to study molecular-level interactions and dynamic microstructure in materials. Direct visualization of single polymer chains has uncovered new ideas regarding the rheology and nonequilibrium dynamics of macromolecules, including the importance of molecular individualism, dynamic heterogeneity, and molecular subpopulations in governing macroscopic behavior. In recent years, the field of single polymer dynamics has been extended to new materials, including architecturally complex polymers such as combs, bottlebrushes, and ring polymers and entangled solutions of long chain polymers in flow. Single molecule visualization, complemented by modeling and simulation techniques such as Brownian dynamics and Monte Carlo methods, allow for unparalleled access to the molecular-scale dynamics of polymeric materials. In this review, recent progress in the field of single polymer dynamics is examined by highlighting major developments and new physics to emerge from thes...
