Abstract

Non-isothermal crystallization kinetics of montmorillonite (MMT)/polyamide 610 (PA610) composites were readily prepared by in situ melt polymerization followed by a full investigation in terms of their microstructure, performance, and crystallization kinetics. The kinetic models of Jeziorny, Ozawa, and Mo were used in turn to fit the experimental data, in all of which Mo's analytical method was found to be the best model for the kinetic data. Differential scanning calorimetry (DSC) and transmission electron microscopy (TEM) studies were used to investigate the isothermal crystallization behavior and MMT dispersion levels in the MMT/PA610 composites. The experiment results revealed that low MMT content can promote the PA610 crystallization, whilst high MMT content result in MMT agglomeration, and reduce the PA610 crystallization rate.

摘要

通过原位熔融聚合轻松制备了蒙脱石（MMT）/聚酰胺610（PA610）复合材料的非等温结晶动力学，随后对其微观结构、性能和结晶动力学进行了全面研究。依次使用Jeziorny、Ozawa和Mo的动力学模型来拟合实验数据，结果发现Mo的分析方法是最适合该动力学数据的模型。采用差示扫描量热法（DSC）和透射电子显微镜（TEM）研究了MMT/PA610复合材料的等温结晶行为和MMT分散水平。实验结果表明，低MMT含量可促进PA610结晶，而高MMT含量会导致MMT团聚，并降低PA610的结晶速率。
