摘要

摘要: 首先通过壬二酸和双(对-羧苯基)苯基氧化膦直接缩聚反应得到半芳香聚酰胺(PA),采用溶液共混方法,以多壁碳纳米管(CNTs)增强PA得到新型纳米复合材料。通过TG-DSC和微尺度燃烧量热法探讨CNTs对复合材料的热性能和可燃性能的影响。当CNT添加量为5%时复合材料的失重率比纯PA提高5%,热分解温度提高70℃。与纯PA相比,复合材料的热释放速率降低,这表明CNTs能提高PA的阻燃性。

Abstract: A novel composite based on a semi-aromatic polyamide (PA) reinforced by multiwall carbon nanotubes (CNTs) was prepared by a solution mixing method. PA was synthesized through a direct polycondensation between azelaic acid and bis (3-amino phenyl) phenyl phosphine oxide. The effect of the CNT addition on the thermal and flammability properties of the composite were studied by thermogravimetric analysis, differential scanning calorimetry and microscale combustion calorimetry. The temperature at which 5% weight loss occurs is increased by over 70℃ by incorporating CNTs into the PA matrix. CNTs improve the flame retardancy of PA, which is manifested by a decrease of the heat release rate and the total heat release of the composite compared with pure PA.
