柔性二维高分子:高分子的新维度
Flexible Two-dimensional Polymers:a New Dimension in Polymer
摘要
Abstract
Compared with one-dimensional(1D)and three-dimensional(3D)polymers,the theory framework of two-dimensional(2D)polymers is still incomplete,especially for flexible 2D polymers.Their unique conformation and properties are one of the mysterious questions in the polymer science.This article comprehensively reviews the theo-retical and simulation research progress of flexible 2D polymers,aiming to systematically sort out the development of the field of flexible 2D polymers from early theoretical prototypes to recent conformational physics research.First,this article reviews theoretical research on tethered membranes from the 1980s.Early molecular dynamics simulations revealed that self-avoidance causes 2D networks to approach a flat state at the thermodynamic limit,rather than undergoing a crumpled transition.Building on this foundation,this article further elaborates on significant break-throughs in the field since the 21st century.Computer simulations have not only validated the scaling relationships between the equilibrium conformations of 2D polymers and their transport properties(such as intrinsic viscosity),but also theoretically unified the long-debated flat and crumpled conformations by introducing an adjustable mesh model,thereby revealing the physical mechanism of their coexistence.Furthermore,a complete conformational evolution path-ranging from flat to multi-level folded,and ultimately to collapsed states has been systematically established.Finally,this article provides an outlook on the opportunities and challenges facing the field,particularly regarding the precise preparation of ordered flexible networks and the utilization of theoretical insights to guide the design of intelligent responsive materials.关键词
