| 摘 要： | 采用5万CiCo-60源进行辐照,制备了乙烯-乙烯醇共聚物TiO2纳米复合材料、SiO2纳米复合材料、ZnO纳米复合材料和有机蒙脱土纳米复合材料。分析了纳米粒子对体系力学性能的影响,研究了辐照剂量、不同基体、不同纳米填料及改性剂等实验条件对体系力学性能的影响。结果表明,以EVOH-68(乙烯醇基含量为68%)为基体的纳米复合材料经过辐照,力学性能明显下降,且下降幅度大。以EVOH-56(乙烯醇基含量为56%)为基体的纳米复合材料经过辐照,在小辐照剂量下力学性能提高,大剂量下力学性能下降,且下降幅度较小。EVOH-56/纳米ZnO体系与EVOH-56/纳米TiO2体系相比表现的更耐辐照。 |

| Abstract: | EVOH/TiO2 nanocomposites,EVOH/SiO2 nanocomposites,EVOH/ZnO nanocomposites and EVOH/MMT nanocomposites were prepared by 60Co.Effects of different radiation,different group,different nano-composites and different experiment conditions on the mechanical properties were discussed.It is found that mechanical properties of irradiated nano-composites based on EVOH-68 decrease dramatically,while the mechanical properties of irradiated nano-composites based on EVOH-56 improve at low radiation doses and decrease at high radiation doses, and in general have small changes.For nano-composites with different nano-fillers,different systems have different reactions to radiation.EVOH-56/nano-ZnO system exhibits better endurance to radiation than EVOH-56/nano-TiO2 system. |
