摘　　要：以氯化钙为络合剂,将聚酰胺6(PA6)粉末与氯化钙溶解在甲酸/氯仿混合溶液中制得冻胶样品,采用DTA、XRD、FTIR、SEM等方法对冻胶结构与性能进行分析,探讨了PA6质量浓度对冻胶样品结构和性能的影响。结果表明,氯化钙可以部分屏蔽PA6的氢键,降低其结晶能力;随着PA6浓度的增大,冻胶样品的分子间作用力增强,熔点升高,不同浓度间的冻胶样品结构和性能以及络合剂的络合效果有一定的差异。Polyamide 6（PA6） gels were prepared by dissolving PA6 powder in formic acid/chloroform cosolvent using calcium chloride as complex agent. Differential thermal analysis（DTA）, X-ray diffraction （XRD）, FT-IR, and scanning eletcron microscopy （SEM） were used to investigate the structure and properties of those gels with different PA6 concentrations. These studies indicated that calcium chloride shielded part intermolecular hydrogen bonds and weakened the crystallization of PA6. With the increase of PA6 concentration, the interaction of molecules in the gels strengthened and the melting temperature of the gels rose. There are some dissimilarity on the structure and properties and the complexation efficiency of calcium chloride among the gels with different concentration.
