This research work focused on the effects of different compatibilizers on the properties of reduced graphene oxide (rGO) reinforced poly(ethylene terephthalate) (PET)/poly(butylene terephthalate) (PBT) nanocomposites. The samples were prepared via melt compounding and injection molding methods. The Joncryl and glycidyl isooctyl polyhedral oligomeric silsesquioxane (GPOSS) were used as compatibilizers at different loading levels (0.5%‐4%). The structural, thermal, mechanical, morphological, and electrical properties of the nanocomposites were investigated. The Fourier transform infrared analysis results revealed that no significant interaction was observed when GPOSS was added. On the other hand, there were more obvious changes in the peaks of the nanocomposite containing Joncryl. The thermal results showed that the compatibilizer addition caused small changes while rGO addition did not considerably affect the thermal stability of blend. The glass transition temperature of the nanocomposite significantly decreased with the addition of GPOSS. The tensile test indicated that compatibilizers improved the mechanical performance of PET/PBT/rGO nanocomposite.

还原氧化石墨烯增强的PET / PBT纳米复合材料：相容性和表征

这项研究工作的重点是不同的增容剂对氧化石墨烯（rGO）增强的聚对苯二甲酸乙二醇酯（PET）/聚对苯二甲酸丁二醇酯（PBT）纳米复合材料性能的影响。样品通过熔融混合和注射成型方法制备。琼脂基和缩水甘油基异辛基多面体低聚倍半硅氧烷（GPOSS）在不同的负载量（0.5％-4％）下用作增容剂。研究了纳米复合材料的结构，热，机械，形态和电性能。傅立叶变换红外分析结果表明，加入GPOSS时未观察到明显的相互作用。另一方面，含有Joncryl的纳米复合材料的峰有更明显的变化。热学结果表明，增容剂的加入引起很小的变化，而rGO的加入并没有显着影响共混物的热稳定性。随着GPOSS的加入，纳米复合材料的玻璃化转变温度显着降低。拉伸试验表明，相容剂改善了PET / PBT / rGO纳米复合材料的机械性能。
