摘要
应用分峰方法计算结晶度,首要条件是结晶聚合物的形态结构必须符合"两相模型"。通过聚合物材料的分析,发现Jade软件的分峰程序固然很好,但其受到扫描范围、基线、非晶峰位置及分布的影响很大,计算的结晶度值有一定的随意性,只能作相对比较,且结晶度值偏大。用X射线衍射法测定的结晶度与其他实验方法获得的结晶度无可比性,还常遇到背景散射的基线不平和非晶峰难以确定等现象。对此进行探讨和交流。
It is very popular for calculating the crystallinity by the peak separation program of Jade software.The chief condition for calculating the crystallinity by this method is that the morphology of the polymer should conform to the "two-phase model system".The peak separation program of Jade software can not be used to calculate the crystallinity of all the polymer materials by testing and analyzing many polymer materials,which is greatly influenced by scan scope,baseline,position and distribution of the amor...
