Effect of Silane Functionalization on the Properties of Iron Oxide Nanoparticles/UP Toughened Epoxy Nanocomposites

Abstract:

Effect of iron oxide nanoparticles (Fe₂O₃) and siliconized iron oxide nanoparticles (Si- Fe₂O₃) on the properties of Unsaturated Polyester (UP) toughened epoxy nanocomposites is investigated in this work. UP toughened based epoxy nanocomposites reinforced with silane functionalized Fe₂O₃ and unmodified Fe₂O₃ nanoparticles were prepared. The silane group functionalization on Fe₂O₃ nanoparticles was confirmed by FT-IR spectroscopy. The impact strength and hardness were studied as per ASTM. The impact strength of the epoxy matrix increased by the reinforcement of Si-Fe₂O₃ nanoparticles which reveals the formation of nanocomposites. Morphology of Si-Fe₂O₃ nanoparticles reinforced UP toughened epoxy nanocomposites was investigated by Scanning Electron Microscope.
