低维度纳米填料(LDCN)具有优异的物理机械性能。研究发现LDCN与聚合物复合,可显著提高复合材料的力学性能或者增加功能,并且LDCN可诱导多种聚合物结晶。LDCN不仅可作为异相成核剂,提高聚合物的结晶温度和结晶速率,而且可诱导聚合物形成特殊的晶体形貌。研究LDCN对聚合物结晶的影响,进而调控聚合物的结晶度和晶体形态,以改善复合材料的多方面性能,具有理论研究和实际应用意义。本文从结晶动力学和结晶形貌两方面综述了LDCN诱导聚合物结晶的研究现状,并阐述了其诱导结晶机理。
Low-dimensional nano-fillers (LDCN) have excellent physical and mechanical properties. It has been found that the combination of LDCN with the polymer can significantly improve the mechanical properties or increase the functionality of the composite, and LDCN can induce crystallization of various polymers. LDCN not only acts as a heterogeneous nucleating agent, increasing the crystallization temperature and crystallization rate of the polymer, but also inducing the polymer to form a special crystalline morphology. Studying the effect of LDCN on the crystallization of polymers, and then regulating the crystallinity and crystal morphology of the polymers to improve the multi-dimensional properties of the composites, has theoretical significance and practical application. In this paper, the current research status of LDCN-induced crystallization of polymers was reviewed from the aspects of crystallization kinetics and crystalline morphology. The mechanism of crystallization induction was also described.
