中文摘要：

利用熔融共混法制备了不同氯化锌（ZnCl2）用量下的聚酰胺6（PA6）／ZnCl2复合材料。分别采用差示扫描量热仪（DSC）、动态力学分析仪（DMA）、电子拉伸机等对不同ZnCl2用量下PA后／ZnCl2复合材料的结晶行为及力学性能进行了研究。结果表明：随着ZnCl2用量的增加，PA6／ZnCl2复合材料的拉伸强度和弯曲强度均呈现先增大后减小的趋势。当ZnCl2质量分数为5％时，复合材料的拉伸强度和弯曲强度分别达到最大值70．39MPa和64．71MPa，较纯PA6分别增加了7．5％和降低了28％；随着ZnCl2用量的增加，PA6／ZnCl2复合材料的玻璃化转变温度逐渐增大，结晶能力下降，结晶度减小，结晶度由原来的34％变为13％。

英文摘要：

PA6/ZnCl2 composites with different ZnCl2 contents were prepared by melt blending method. PA6/ZnCl2 composites were characterized by differential scanning calorimetry （DSC）, Dynamic mechanical analyzer（DMA）and electronic tensile machine. The crystallization behavior and mechanical properties of PA6 / ZnCl2 composites with different ZnClz contents were studied. The results show that tensile strength and flexural strength of PA6/ZnCl2 composites increase first and then decrease with the increase of ZnCl2 content. When the mass fraction of ZnCl2 is 5% ,the tensile strength and flexural strength of PA6/ZnCl2 composites respectively reach the maximum value of 70. 39 MPa and 64. 71 MPa, compared with pure PA6 increased by 7. 50/oo and decreased by 28%. With the increasing of ZnCl2 content,the glass transition temperature of PA6/ZnCl2 composite gradually increases,while crystallization ability and the crystallinity decreases. The erystallinity decreases from 34% to 13%.
