Abstract

Tetra functional epoxy resin namely tetraglycidyl 1,4’-bis (4-amine-phenoxy) sulphone benzene epoxy (TGBAPSB) was developed via 1,4’-bis (4-amine-phenoxy) sulphone benzene (BAPSB) and epichlorohydrin. TGBAPSB was reinforced with polyhedral oligomeric silsesquioxane (POSS) nanomaterial in various weight percentages (1–2 wt%) and polyamidoimidazoline (Aradur 140) was used as curing agent. FT-IR results validated the molecular structure of the synthesized POSS. Dynamic mechanical analysis (DMA) and thermogravimetric analysis (TGA) evaluated the thermo-mechanical and thermal behaviour of TGBAPSB epoxy matrix and its organic-inorganic hybrid epoxy nanocomposites (TGBAPSB/POSS). X-Ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) investigated the surface morphological behaviour of the organic-inorganic hybrid epoxy nanocomposites. TGBAPSB epoxy resin with optimized POSS reinforcement exhibited excellent thermo-mechanical, thermal, mechanical, dielectric, and water absorption properties, making it a suitable material for advanced high-performance applications.

四官能团环氧树脂/多面体低聚硅氧烷(POSS)纳米复合材料具有增强的机械、热、防腐和介电性能

以1,4′-双(4-胺-苯氧基)磺苯(BAPSB)和环氧氯丙烷为原料，制备了四功能环氧树脂——四缩水甘油酯1,4′-双(4-胺-苯氧基)磺苯环氧树脂(TGBAPSB)。采用不同重量百分比(1-2 wt%)的多面体低聚硅氧烷(POSS)纳米材料和聚酰胺咪唑啉(Aradur 140)作为固化剂对TGBAPSB进行增强。FT-IR结果验证了合成的POSS的分子结构。动态力学分析(DMA)和热重分析(TGA)评价了TGBAPSB环氧基及其有机-无机杂化环氧纳米复合材料(TGBAPSB/POSS)的热力学和热行为。x射线衍射(XRD)、扫描电镜(SEM)和透射电镜(TEM)研究了有机-无机杂化环氧纳米复合材料的表面形态行为。具有优化POSS增强的TGBAPSB环氧树脂具有优异的热机械，热，机械，介电和吸水性能，使其成为先进高性能应用的合适材料。
