내용
Polymeric liquids underpin a broad range of contemporary products and are routinely processed under diverse flow fields. Their macroscopic rheology is governed by flow-induced microstructural evolution and the underlying dynamics of chain molecules, making a quantitative understanding of structure-property coupling essential for both polymer processing and fundamental polymer physics. Because these responses span wide ranges of time and length scales, they cannot be represented adequately by a single constitutive model. Instead, hierarchical multilevel frameworks are required, in which atomistic, mesoscopic, and continuum descriptions capture the dominant physics at their respective scales. This talk reviews recent advances in multiscale simulation methodologies for polymeric liquids and discusses strategies for systematic coarse-graining and cross-scale integration toward unified, predictive interpretations of polymer rheology.
