本研究的主要目的是制备石墨烯纳米片（GP）和蒙脱土纳米粘土（MMT）二元填料改性的环氧聚合物复合材料。将不同负载百分比的单个和二元纳米填料掺入到环氧树脂基体体系中，以研究纳米填料对复合材料性能的协同效应。采用动态力学分析（DMA）和三点弯曲试验研究了纯环氧树脂和纳米填料增强纳米复合材料的粘弹性能和弯曲性能。加入3 wt. %的MMT和0. %的GP导致更好的弯曲强度、模量和储能模量，尽管玻璃化转变温度（Tg）没有显著变化。
The prime objective of this study was to fabricate epoxy polymer composite modified with graphene nanoplatelets (GP) and montmorillonite nanoclay (MMT) binary filler materials. Different loading percentages of individual and binary nanofillers were incorporated into an epoxy matrix system to investigate the synergistic effect of nanofillers on composites properties. Dynamic mechanical analysis (DMA) and three point bend test were carried out to investigate the viscoelastic and flexural properties of neat epoxy and nanofillers reinforced nanocomposites. Incorporation of 3 wt. % of MMT and 0.1 wt. % of GP resulted in better flexure strength, modulus and storage modulus although there is no significance change in glass transition temperature (Tg).
