The mechanical properties and morphology of polyamide 6/maleic anhydride grafted ethylene-co-vinyl acetate (PA6/EVA-g-MA) ternary composites are considered a function of compatibilizer (EVA-g-MA) amount at a mixing combination of 20 wt% dispersed phase (combination of EVA and the compatibilizer). 1–7 wt% compatibilizer are added to PA6/EVA-g-MA, whereas the PA6 doping is kept constant at 80 wt% in the ternary composites. Furthermore, 0.5, 1, 3, and 5 wt% octa-Isobutyl POSS (OIP) is used for reinforcement. The thermal, mechanical, and morphological properties of PA6/EVA-g-MA composites have been studied through DSC, TGA, DMTA, traditional mechanical measurements, and SEM. Tensile strength and Young’s modulus declined by increasing the compatibilizer concentration. The impact strength of PA6/compatibilizer improved considerably up to 3 wt% of the compatibilizer and then decreased. TGA analysis demonstrated a considerable improvement in the thermal stabilities of the nanocomposites by raising the OIP amount. The results of DMTA, including Tg, and DSC analysis demonstrated that the inclusion of OIP in PA6/compatibilizer considerably changed the thermal properties of only PA6 in PA6/compatibilizer. Incorporating OIP into the composite up to 1 wt% improved its modulus, tensile, and impact strength.

增容剂和多面体低聚倍半硅氧烷对聚酰胺6/聚（乙烯-共-乙酸乙烯酯）复合材料机械、热和形态性能的影响

聚酰胺 6/马来酸酐接枝乙烯-醋酸乙烯酯 (PA6/EVA-g-MA) 三元复合材料的机械性能和形貌被认为是 20 wt 混合组合下增容剂 (EVA-g-MA) 用量的函数％分散相（EVA 和增容剂的组合）。PA6/EVA-g-MA 中添加了 1–7 wt% 的增容剂，而三元复合材料中 PA6 的掺杂量保持在 80 wt%。此外，还使用 ​​0.5、1、3 和 5 wt% 八异丁基 POSS (OIP) 进行增强。通过 DSC、TGA、DMTA、传统机械测量和 SEM 研究了 PA6/EVA-g-MA 复合材料的热、机械和形态性能。通过增加增容剂浓度，拉伸强度和杨氏模量下降。PA6/增容剂的冲击强度在增容剂含量达到 3 wt% 时显着提高，然后下降。TGA 分析表明，通过提高 OIP 用量，纳米复合材料的热稳定性得到了显着改善。DMTA的结果，包括TG，DSC 分析表明，PA6/增容剂中添加 OIP 显着改变了 PA6/增容剂中仅 PA6 的热性能。在复合材料中加入高达 1 wt% 的 OIP 可提高其模量、拉伸强度和冲击强度。
