摘　　要：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 carbon nanofillers （LDCN） have outstanding mechanical properties. It has been reported that adding LDCN into polymers can improve mechanical properties or enhance function of the composites and LDCN can also induce kinds of polymers crystallization. Not only are the crystallization temperatures and crystallization rates of polymers elevated by the presence of LDCN acting as nucleating agents, but unique crystalline morphology may also be induced to form. There are great significance of theoretical research and practical application to investigate the effect of LDCN on crystallization of polymers. It is expected that kinds of properties of LDCN/polymer composites are improved by regulating crystallinity and crystalline morphology of the polymers. The research progress in LDCN inducing polymer crystallization was summarized in crystallization kinetics and crystalline morphologies. Moreover, their inducing mechanism was also discussed.
