The Global and Local Properties of Polymers Zhu Pingping, He Pingsheng, Yang Haiyang Abstract The global and local properties of polymers are not only
fundamentally different but also strongly related. As a result, the morphology, molecular
movements, condensed state and physical properties of polymers are quite different from
those of small molecules. In this article, the global flexibility and local rigidity,
polymer chains and segments, global random and local order, global independent blobs and
local correlations of a Flory chains are presented to discuss the global and local
properties of polymers.
高分子中的整体与局部 朱平平 何平笙 杨海洋 摘要 高分子中的整体与局部之间差别很大同时又相互关联,由此导致高分子在形态、分子运动、凝聚态结构和物理性能等方面明显地有别于小分子。本文从高分子中的整体柔性与局部刚性、高分子整链和链段、整体无序而局部有序以及大区域不溶胀而小区域溶胀四个方面对高分子中的整体性质与局部性质展开了较为详细的讨论。关键词 高分子链 链段 柔性 无规线团 凝聚缠结 朱平平 女,38岁,副教授,主要从事高分子溶液、共混高聚物性能等方面的研究。E-mail:zhupp@ustc.edu.cn2002-07-01收稿,2002-12-18修回 |
