结晶度(crystallinity,degree of crystallinity),表征聚合物中结晶部分占全部聚合物的比例,用一个公式表示为:结晶度=结晶部分/(结晶部分+非结晶部分)。 表征聚合物材料结晶度的手段有很多,最先想到的是DSC方法: 基本的原理:聚合物熔化即反映了聚合物结晶部分的热行为,聚合物熔融热与结晶度成正比,结晶度越高,熔融热...

A large number of polymers are able to form crystalline structures in which parts of the macromolecules are orientated parallel to one another. Unlike low molecular weight substances, the degree of crystallinity that can be achieved by polymers is much lower than 100 percent and depends on the mo...
