The effects of silanized sepiolite (SP) and electron beam (e-beam) irradiation on the physico-mechanical properties of ethylene-vinyl acetate copolymer (EVA)/ternary polyamide (tPA) composites were studied. SP was silanized with vinyltriethoxysilane (VTES) to enhance the dispersion and compatibility of the inorganic filler into the EVA/tPA matrix. The crosslinking of EVA/tPA by e-beam irradiation was carried out ranging from 50 to 250 kGy. The prepared composite films were characterized for change in morphology, mechanical properties, crosslinking effect on crystallinity and swelling using various established analytical techniques. Experimental results indicated that tensile strength of irradiated composite EVA/tPA/m-SP5 (70/30/5) was 3 times higher than that of virgin composite film at an absorbed dose of 250 kGy. The storage modulus of EVA/tPA/m-SP5 (70/30/5) composite film was significantly increased with the increase of absorbed dose. However, melting and crystallization temperature of EVA/tPA composites slightly decreased with the increase of absorbed dose. Moreover, the modification of SP with VTES and irradiated composite films were subjected to oil swelling studies.

研究了硅烷化海泡石 (SP) 和电子束 (e-beam) 辐照对乙烯-醋酸乙烯共聚物 (EVA)/三元聚酰胺 (tPA) 复合材料物理机械性能的影响。SP 用乙烯基三乙氧基硅烷 (VTES) 进行硅烷化，以提高无机填料在 EVA/tPA 基体中的分散性和相容性。通过电子束辐照 EVA/tPA 的交联在 50 至 250 kGy 范围内进行。使用各种已建立的分析技术表征制备的复合膜的形态变化、机械性能、交联对结晶度和溶胀的影响。实验结果表明，在吸收剂量为 250 kGy 时，辐照复合 EVA/tPA/m-SP5 (70/30/5) 的拉伸强度是原始复合膜的 3 倍。EVA/tPA/m-SP5（70/30/5）复合薄膜的储能模量随着吸收剂量的增加而显着增加。然而，EVA/tPA 复合材料的熔化和结晶温度随着吸收剂量的增加而略有下降。此外，用 VTES 和辐照复合膜对 SP 的改性进行了油溶胀研究。
