聚合物共混的形态

你说的应该是聚合物共混物的“微观”形态结构吧？宏观的，就自己眼睛看。。

一般微观结构用的比较多的是SEM和TEM（就是扫描电镜和透射电镜），如果还不行还可以用相差电镜或者原子力（AFM）。

一般SEM最常用，共混之后压片，如果看内部结构，在液N中淬断，SEM看断面形态。如果看表面就直接后压片后看。看SEM一般都要先喷金。原理我就不想说了，自己去搜吧，二次电子。。。。了解了原理其实也没什么帮助。

SEM一般看聚合物填充粒子之类的东东。只不过有些时候SEM看不出来什么东西，比如两种聚合物有两相结构之类，这时可以用TEM，做超薄切片，然后染色，看两相形态。也可以用相差，如果两相硬度差别很大，也可以用AFM。只不过AFM制样要求很高，聚合物一般表面做不到这么平。

At the same temperature was reviewed in this paper, the speed to the nylon 6 different proportion of calcium sulfate whisker, after twin-screw mixing extruding machine, extrusion, mixed granulation, created by injection spline, Then on spline on tensile strength, bending strength, no gap in the impact strength, impact strength, gap and shall melt index length-diameter ratio and so on a series of performance testing, Low temperature quenching of spline, by SEM get whisker and polymer interface structure model, Finally, we summarize and analysis of data. In theory, the study of modified whisker properties of nylon 6, according to the data structure and material, explore new modified formula. In application, looking for a better, more practical process.
