| 摘 要： | 在外力作用下,半结晶聚合物的结晶形态、结晶动力学等与静态条件下相比,均发生了较大的变化,并继而影响到成型制品的性能.自上世纪六十年代人们从溶液中发现外力诱导结晶现象以来,相继开展了大量相关的理论和实验研究,提出了一些模型,随着测试手段的改进,流动诱导结晶研究取得了较大的进展,但仍存在许多争议.本文回顾了围绕聚合物流动诱导结晶所开展的工作,重点综述了流动诱导结晶形态变化、分子量及其分布、剪切速率、温度等因素对聚合物结晶动力学的影响,并指出了今后的研究方向. |
| 关 键 词： | 流动诱导结晶 晶体形态 剪切速率 过冷度 结晶动力学 |

| Abstract: | Under external force,the morphology and kinetics of semi-crystalline polymers are quite different from that of quiescent conditions. Furthermore,such differences can influence the properties of final products. Since the observation of outer force induced crystallization in solution from the 1960s,lots of experiments have been conducted and related models have been posed in this subject. Along with the development of testing methods,much more advancements have been obtained in flow-induced crystallization,bu... |
