Graphite nanoparticles (GNPs) as a filler for the purpose of reinforcing epoxy were synthesized via electrochemically oxidizing route. In the as-prepared GNPs were introduced certain oxygen functional groups, with crystalline structure of graphite partially remained. GNPs could be exfoliated and well dispersed into the epoxy matrix with the aid of ultrasonic processing technique. The addition of GNPs has enhanced the thermal stability of epoxy by ca. 19 ℃, together with the 17 MPa and 6 % improvements of mechanical strength and toughness, respectively, with 5 wt.% GNPs loading.

| As a filler for the purpose of reinforcing epoxy, graphite nanoparticles (GNPs) were synthesized via electrochemically oxidizing route. In the as-prepared GNPs certain oxygen functional groups were introduced, with partially ordered crystalline structure of graphite. GNPs could be exfoliated and well dispersed into the epoxy matrix with the aid of ultrasonic processing. The addition of GNPs enhances the thermal stability of epoxy by ca. 19 ℃, along with about 6 % improvement of mechanical strength and toughness to 17 MPa, with 5 wt.% GNPs loading. |
