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1.0mol/L NaOH标准溶液中水解10d后n-HA含量越高,水解越快。
A new unsaturated poly(ester-amide)resin was synthesized and characterized,and nanohydroxyapatite(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 3months of the degradation.After a hydrolysis in a 1.0mol/L NaOH standard solution for 10 days,the more the n-HA content,the higher the rate of hydrolysis.
