聚合物外延生长定义了过度生长的聚合物的晶体取向。它控制半结晶聚合物结构的几个方面，如固定的相互链取向，多晶型聚合物的某些晶体结构，以及平面骨架分子链的空间排列。因此，外延结晶提供了一种简单而有效的方法来制造具有改进性能的特殊结构，甚至为聚合物材料引入新的功能。除了实现单一聚合物体系的结构控制外，多相和多组分聚合物体系的结构和形态操纵领域的技术发展是聚合物材料先进应用的另一个重要且具有挑战性的问题。
Polymer epitaxy defines the crystallographic orientation of overgrowing polymer. It controls several aspects of the structure of semicrystalline polymers, such as fixed mutual chain orientation, certain crystal structures of polymorphic polymers, and the spatial arrangement of planar backbone molecular chains. Therefore, epitaxial crystallization provides a simple and efficient way to fabricate special structures with improved properties and even introduce new functionality for polymeric materials. Besides achieving structural control of single polymer systems, technical development in the field of structural and morphological manipulation of multiphase and multicomponent polymer systems is another important and challenging issue for the advanced application of polymeric materials.
