摘　　要：聚酯酰胺具有良好的机械性能和降解性,利用无机纳米材料可以改善聚合物的机械性能。利用纳米材料的增强作用原位复合多壁碳纳米管,制备聚酯酰胺和碳纳米管复合材料,对其复合行为和性能进行研究。考察多壁碳纳米管在聚酯酰胺中的分散,测试复合材料的热性能、机械性能以及复合材料吸水和降解性能。结果表明:多壁碳纳米管可以在聚酯酰胺中均匀分散,复合材料拉伸强度和断裂伸长均增加,降解性保持。Polyesteramides have good mechanical properties and degradability, so using inorganic nanometer materials can improve the mechanical properties of the polymer. In this paper, PEA/MWNTs were synthesized in-situ using the reinforcement of nano-composite, We observed the dispersion of multi-walled carbon nanotubes in polyesteramides, and tested the nano- composite thermal, mechanical, water absorption and degradation properties of the material. The results show that multi-walled carbon nanotubes in polyesteramides can be uniformly dispersed, and that the tensile strength and elongation at break increase and its degradation remains at the same level.
