Abstract The effect of Closite C93A nanoclay on the mechanical, thermal properties of diglycidyl ether bisphenol A (DGEBA) epoxy resin and epoxidized soybean oil (ESO) bioepoxy blend at various wt.% (10, 20, 30) cured with anhydride hardener (MHHPA) existence of 2-methylimidazole (2-MI) as an accelerator was investigated. The DGEBA/ESO blend systems optimized through the mechanical properties. The 20 wt.% DGEBA/ESO blend systems exhibited higher tensile and impact strength incorporation of 0.5–2.5 wt.% C93A nanoclay. The curing reaction of DGEBA blends and its nanocomposites with MHHPA, 2-MI was explored by non-isothermal differential scanning calorimetry (DSC). The thermal stability of DGEBA/20%ESO blend enhanced by loading of 2.5 wt.% C93A nanoclay which restrict the flexibility of chain and obstructed the decomposition process. The formation of exfoliated inside the clays in the DGEBA/ESO/2.5%C93A nanocomposites corroborated by X-ray diffraction (XRD) and transmission electron microscopy (TEM) analysis. Graphical Abstract

环氧化大豆油 (ESO) 基环氧树脂 (DGEBA) 混合物和粘土片的纳米复合材料：用甲基六氢邻苯二甲酸酐交联剂固化

摘要 Closite C93A 纳米粘土对二缩水甘油醚双酚 A (DGEBA) 环氧树脂和环氧化大豆油 (ESO) 生物环氧树脂共混物在不同重量百分比 (10, 20, 30) 下用酸酐硬化剂 (MHHPA) 固化的影响) 研究了 2-甲基咪唑 (2-MI) 作为促进剂的存在。通过机械性能优化的 DGEBA/ESO 混合系统。20 wt.% DGEBA/ESO 共混体系表现出更高的拉伸和冲击强度结合 0.5-2.5 wt.% C93A 纳米粘土。通过非等温差示扫描量热法 (DSC) 研究了 DGEBA 共混物及其纳米复合材料与 MHHPA、2-MI 的固化反应。DGEBA/20% ESO 混合物的热稳定性通过加载 2.5 wt.% C93A 纳米粘土而增强，这限制了链的柔韧性并阻碍了分解过程。X 射线衍射 (XRD) 和透射电子显微镜 (TEM) 分析证实了 DGEBA/ESO/2.5%C93A 纳米复合材料中粘土内部剥落的形成。图形概要
