| 摘 要： | 用硅烷偶联剂y-氨丙基三乙氧基硅烷（KH550）对纳米SiO2进行改性，采用熔融共混法制备了合SiO2的质量分数为5％的乙烯-乙烯醇共聚物（EVOH）／纳米SiO2复合材料，并吹塑成薄膜，将复合膜进行不同时间、不同强度的紫外辐照处理。利用FTIR、TEM、SEM对纳米SiO2和复合材料进行了表征分析，测试了复合材料紫外辐照处理前后的阻隔性能和力学性能。结果表明：纳米SiO2与偶联剂KH550形成化学键合，经紫外辐照处理的EVOH／纳米SiO2复合膜的力学性能、阻隔性能得到了较大地提高。

| Abstract: | Nano-SiO2 modified by y -aminopropyl triethoxysilane（KH550） was used to prepare the ethylene-vinyl alcohol copolymer（EVOH）/nano-SiO2 composites through melt-compounding method and the composites were blown into films. The films were treated by UV irradiation with different treating time and intensity. Nano-SiO2 was characterized by FT-IR, TEM and SEM, the barrier properties and mechanical properties of treated and untreated composites were tested. The results showed that chemical bonds were formed between nano-SiO2 and silane coupling agent KH550, and the barrier properties, mechanical properties of the EVOH/nano-SiO2 composites were improved greatly. |
