Surface modification of magnesium oxide/epoxy composites with significantly improved mechanical and thermal properties

This work demonstrated the effect of functionalized magnesium oxide (MgO) nanoparticles with 3-(aminopropyl) triethoxysilane (APTES) as fillers on mechanical and thermal properties epoxy composite. The functionalization MgO (S-MgO) considerably improved interface between resin. composites revealed that addition their tensile strength, modulus elasticity, ductility when compared to neat epoxy. In comparison epoxy, in-plane conductivity composite S-MgO filler is by 10 folds. These observations indicated silane contributes formation a strong interfacial bond compact interconnected network matrix.
