(657d) Magnetic Epoxy Nanocomposites Reinforced with Core-Shell Structured Fe@FeO Nanoparticles

Magnetic epoxy nanocomposites reinforced with various loadings of core-shell Fe@FeO structured nanoparticles are prepared. Nanoparticle loading effect on the viscosity of the resulting nanocomposite suspension is studied at different shear rates and temperatures. Dynamic mechanical analysis (DMA) results reveal that the glass transition temperature is increased with the addition of nanoparticles and the tensile test results show the well maintained mechanical strength even at high particle loadings. The related magnetic properties, electrical conductivity and the thermal stability are also reported.
