摘要：

High functional epoxy nanocomposites with three different filler materials, i.e., B4C, PbO, and Al(OH)(3), were fabricated using an effective fabrication method consisting of an ultrasonic dispersion of nanopartides in low-viscosity hardener and a subsequent mixing of a hardener-nanoparticle colloid with epoxy resins. It was confirmed that this approach provided not only an uniform dispersion but also an excellent wetting with enhanced interfacial adhesion of nano-particulate fillers within the matrix. By incorporating those three fillers, a synergistic effect was verified in multiple properties such as mechanical strength properties, thermal degradation, flame retardancy, and radiation shielding performance.
