摘要: Novel multifunctional graphene@Fe3O4 hybrid nanofluid with liquid-like behavior at room temperature and low viscosity (5.5 Pa.s 25°C) has been developed by using GO@Fe3O4 as a core, sulfuric acid-terminated organosilanes corona, polyether amine canopy. The obtained extensively characterized various analytical techniques. content of reaches up to 13.78 wt% in the nanofluid, which is superparamagnetism material specific magnetization 0.39 emu/g. In addition, it shows excellent dispersion exfoliation solvents polymer matrixes. It then compounded an epoxy resin for development nanofluid/epoxy nanocomposites. found that nanocomposites demonstrate better mechanical property than those unmodified graphite/epoxy same fraction. For example, 1.5 improves impact toughness 125%. This new interface modification also enhanced Tg neat from 98.37 129.46°C. POLYM.
