结晶高聚物硬弹性材料的研究进展─—Ⅱ．硬弹性材料的形态和结构

Development of Crystalline Polymer Hard Elastic Materials ─ Ⅱ.Morphology and Structure of Hard Elastic Materials

硬弹性材料特殊的力学性能是由其特殊的形态和结构决定的，不同的加工条件可以大大影响材料内部的形态和结构，进而影响材料的表观物理性能。本文主要介绍了这种材料的结晶与取向，表面形态及拉伸过程中结构的变化。

he typical mechanical properties of hard elastic materials are the results of their structure and morphology.The different processing conditions can greatly affect the inner structure and morphology of these materials,and further affect their mechanical properties.This paper mainly discusses crystalline and orientation,morphology and structural changes upon deformation of these materials.
