| Abstract |
Hybrid fillers composed of nanodiamond (ND) decorated graphene oxide (GO) were incorporated into epoxy matrix with a novel thermoregulatory liquid-liquid extraction method. Energy dispersive spectroscopy, X-ray diffraction spectroscopy, Fourier transform infrared and X-ray photoelectron spectroscopy analysis confirmed chemical bonding between the 3-aminopropyltriethoxysilane functionilizatied nanodiamond (ND-APTES) and 3-Glycidoxypropyltrimethoxy silane functionalized graphene oxide (GO-GMPTS). The morphology of the hybrid filler, GN was characterized by high-resolution transmission electron microscopy. ND nanoclusters with an average diameter of 50-100nm were uniformally grown on the GO surface. The hybrid filler provided significant enhancement of mechanical properties, such as flexural strength, flexural modulus and impact strength. In particular, the epoxy composites containing 0.1wt% hybrid GN exhibited a higher mechanical behavior compared to the one containing 0.2 wt% GO. |
