可降解聚酯酰胺纳米复合材料的制备与表征

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。

Characteristics and Preparation of Degradable Polyesteramide Nano Polymer

Polyesteramides have good mechanical properties and degradability，so using inorganic nanometer materials canimprove the mechanical properties of the polymer. In this paper，PEA/MWNTs were synthesized in-situ using the reinforcementof nano-composite. We observed the dispersion of multi-walled carbon nanotubes in polyesteramides，and tested the nanocompositethermal，mechanical，water absorption and degradation properties of the material. The results show that multi-walledcarbon nanotubes in polyesteramides can be uniformly dispersed，and that the tensile strength and elongation at break increaseand its degradation remains at the same level.
