摘要: 通过熔融缩聚法合成了一种不饱和聚酯酰胺树脂,并用纳米羟基磷灰石(n-HA)进行增强,研究了其弯曲和降解性能。结果表明,不饱和聚酯酰胺树脂有优良的热稳定性;随n-HA含量增加,复合材料弯曲性能有一定升高,但当n-HA含量超过10 %时弯曲性能反而降低;在前3个月的降解过程中,高n-HA含量的纳米复合材料更能降低力学性能衰减率及减少质量损失率;纳米复合材料在1.0 mol/L NaOH标准溶液中水解10 d后n-HA含量越高,水解越快。

Abstract: A new unsaturated poly(ester-amide)resin was synthesized and characterized, and nano-hydroxyapatite(n-HA)was used to strengthen unsaturated poly(ester-amide).UPEA possessed an excellent thermal stability. Upon being loaded with n-HA, the flexural property of UPEA increased. When the n-HA content exceeded 10 %, flexural properties decreased. However, a high content of n-HA may reduce the decay rate and mass loss rate during the first 3 months of the degradation. After a hydrolysis in a 1.0 mol/L NaOH standard solution for 10 days, the more the n-HA content, the higher the rate of hydrolysis.
