关于等规聚丙烯球晶的结构,已由Padden和Keith用电镜作了详细的观察。但是从透射电镜所得的照片是一个平面图象,对于了解球晶的整体结构,需要作适当的推论。扫描电镜的优点是能够得出景深较好的图象,立体感较强,缺点是只能反映样品外表的形态,要得到能显示内部结构的照片,则需要蚀刻,一般说要准确掌握这些技术比较困难,因此这方面的工作不多。 The structure of isotactic polypropylene spherulites has been examined electronically by Padden and Keith. However, a photograph taken from a TEM is a flat image, and the corollary to the overall structure of spherulites needs to be properly inferred. Scanning electron microscopy has the advantage of being able to draw a better image of the depth of field, strong three-dimensional, the disadvantage is that it only reflects the appearance of the sample appearance, to get to show the internal structure of the photos, you need to etch, in general, accurate grasp of these technologies More difficult, so there is not much work in this area.
