Using a melt-mixing technique, ethylene–vinyl acetate (EVA) copolymers based composites containing Multi-Wall Carbon nanotubes (MWCNTs), aluminum trihydrate (ATH), zinc borate (ZB), and gadolinium oxide (Gd2O3) were fabricated. Then, the as-prepared samples were irradiated with an electron beam (EB) at the dose range varied from 0 to 275 kGy. Moreover, we investigated the properties of irradiated and unirradiated samples. Morphological observation showed good dispersion of MWCNTs and other additives in EVA. Furthermore, the gel content, mechanical properties, the limit oxygen index (LOI) values of irradiated composites increased to 28.4% after 250 kGy after irradiated. All the conclusions indicated that the comprehensive properties of the WMCNTs/EVA composites were improved by using high energy electron beam irradiation.

高能电子束辐照的EVA / MWCNTs中子屏蔽复合材料的机械和阻燃增强

使用熔融混合技术,基于乙烯-乙酸乙烯酯(EVA)共聚物的复合材料包含多壁碳纳米管(MWCNT),三水合铝(ATH),硼酸锌(ZB)和氧化g(Gd 2 O 3)被捏造。然后,以0至275kGy的剂量范围用电子束(EB)辐照所制备的样品。此外,我们研究了辐照和未辐照样品的特性。形态观察表明,MWCNT和其他添加剂在EVA中分散良好。此外,辐照后的复合材料在250 kGy辐照后,其凝胶含量,机械性能和极限氧指数(LOI)值均增至28.4%。所有结论表明,高能电子束辐照改善了WMCNTs / EVA复合材料的综合性能。
