| 摘 要： | 通过熔融共混法制备了高密度聚乙烯/超高分子量聚乙烯/纳米羟基磷灰(石HDPE/UHMWPE/纳米HA)生物复合材料,研究了增容剂三元乙丙橡胶接枝马来酸(酐EPDM-g-MAH)和聚烯烃弹性体接枝马来酸酐(POE-g-MAH)对复合材料力学性能的影响,并利用红外光谱、扫描电镜、热重分析仪及熔体流动速率仪表征了复合材料的微观结构、热性能和流动性能。结果表明:EPDM-g-MAH和POE-g-MAH均可提高HDPE/UHMWPE/纳米HA复合材料的相容性,其中EPDM-g-MAH的增容效果更明显;随着增容剂用量的增大,复合材料的熔体流动速率、热变形温度和热稳定性逐渐下降;与添加POE-g-MAH相比,含有EPDM-g-MAH的复合材料的综合性能较好。

| Abstract: | The biomaterial composites of HDPE/UHMWPE/nano-hydroxyapatite(nano-HA) were prepared by means of melt blending.The effects of compatibilizers(EPDM-g-MAH and POE-g-MAH) on mechanical properties of HDPE/UHMWPE/nano-HA composite were investigated.The microstructure,melt flowability and thermal stability of the composite were characterized by IR,SEM,TGA and MFR.The results show that both EPDM-g-MAH and POE-g-MAH can improve the compatibility of HDPE/UHMWPE/nano-HA composite,wherein the compatibilization effect ... |
