摘　　要：采用FTIR、Molau实验 ,SEM ,力学性能及阻隔性能测试方法 ,研究了γ射线辐照对高密度聚乙烯(HDPE) /尼龙 6(PA6)共混体系的影响。结果表明 ,采用γ射线对HDPE进行辐照 ,在其分子链上引入了含氧极性基团 ,增加了HDPE分子的极性 ,改善了HDPE/PA6共混体系的相容性 ,提高了该共混体系的力学性能和对二甲苯的阻隔性能。FTIR, Molau test , SEM, mechanical properties and barrier property determinations were used to the study of the effect of γ-ray irradiation on the structure and property of HDPE/PA6 blend. The experimental results showed that some oxygen-containing polar groups were introduced onto the molecular chains of HDPE by γ-ray irradiation, the polarity of HDPE molecular was thus improved, resulted in the improvements of the compatibility and the increase of the barrier property to dimethyl benzene of the HDPE/PA6 blend.
