半结晶聚合物的结构和形态对性能的依赖性提供了通过结构控制来定制这些材料的性能的有效途径。为此,建立结构和财产关系至关重要。为了正确表征晶体结构,可以使用几种技术。在这些技术中,电子衍射具有确定与特定形成条件相关的晶体结构的优势,因为它可以联合收割机与样品的明场和暗场观察相结合。这篇专题文章以精心挑选的例子说明电子衍射在测定半结晶聚合物晶体结构中的应用。重点介绍了电子衍射技术在揭示高分子晶体结构、不同晶体间的相互取向以及高分子晶体中的无序等方面的应用。
The dependence of properties on the structure and morphology of semicrystalline polymers offers an effective way to tailor the properties of these materials through structure control. To this end, establishing the structure and property relationship is of great importance. For a right characterization of the crystal structure, several techniques can be used. Among these techniques, electron diffraction has its advantage for determining the crystal structure related to specific formation condition since it can combine with bright and dark fields observation of the sample. This feature article describes the application of electron diffraction in determining the crystal structure of semicrystalline polymers with elaborately selected examples. We focus on how the electron diffraction can be used to disclose the crystal structure, mutual orientation of different crystals, as well as the disorders included in the polymer crystals.
