人们一直在为制备聚合物宏观单晶体而努力探索着。 多少年来,所制得的聚合物都是非晶或半晶的。50年代Keller从稀溶液(<0.01％)中培养得了微米量级的聚乙烯晶片,是一个重大的突破,随后几乎所有能结晶的聚合物都得到类似的晶片,它们具有垂直于晶片的折叠链结构,链的折叠部分破坏了晶体的三维有序,晶体结构并不完整。因此聚乙烯等晶片的出现仍然不是聚合物宏观单晶体,甚至由于结晶性聚合物的折叠链结构是如此地普遍,在一个时期里竟认为不存在完整的聚合物单晶。
People have been working for the preparation of macroscopic polymer single crystal and hard to explore. For many years, the polymers produced were either amorphous or semi-crystalline. In the 1950s Keller had a major breakthrough in micron-scale polyethylene wafers grown from dilute solutions (<0.01%), and then almost all of the crystallizable polymers gave similar wafers with folded chains perpendicular to the wafer Structure, the folded part of the chain destroyed the three-dimensional crystal order, the crystal structure is not complete. Thus, the appearance of wafers such as polyethylene is still not macro macromolecules of the polymer. Even though the folding chain structure of the crystalline polymer is so common, in a period of time it is thought that there is no complete single crystal of polymer.
