最近的实验研究进行了广泛的审查，在空间上被限制在小域与他们的尺寸在10 nm的顺序（nanodomains）的聚合物链的结晶，特别强调的结晶行为和晶体取向的独特功能的限制链。这里采用的纳米畴（如纳米球、纳米柱或纳米乳）主要由二嵌段共聚物的微相分离提供，因此我们引入嵌段链的结晶（即，其中一个链端总是束缚在纳米畴界面处的聚合物链）。受限嵌段的结晶是非常复杂的，因此与本体均聚物的结晶相比是有趣的，因为它显著地取决于纳米畴的形状、尺寸和硬度以及嵌段链的结晶性质。此外，我们讨论了嵌段链和均聚物之间结晶行为和晶体取向的实质性差异（即，两个链端都自由的聚合物链）在空间上被限制在相同的纳米畴中。(C)2015爱思唯尔有限公司版权所有。
Recent experimental studies are extensively reviewed on the crystallization of polymer chains spatially confined in small domains with their dimension on the order of 10 nm (nanodomains), with a particular emphasis on unique features of crystallization behavior and crystal orientation of confined chains. The nanodomains employed here (such as nanospheres, nanocylinders, or nanolamellae) are mainly provided by the microphase separation of diblock copolymers, and therefore we introduce the crystallization of block chains (i.e., polymer chains with one of chain-ends always tethered at nanodomain interfaces). The crystallization of confined blocks is very complicated and hence interesting as compared with that of bulk homopolymers, because it depends significantly on the shape, size, and hardness of nanodomains as well as the crystalline nature of block chains. Furthermore, we discuss a substantial difference in the crystallization behavior and crystal orientation between block chains and homopolymers (i.e., polymer chains with both chain-ends free) spatially confined in identical nanodomains.
