In-situ bonding technology and excellent anticorrosion activity of graphene oxide / hydroxyapatite nanocomposite pigment

In-situ bonding technology is designed for massively fabricating graphene oxide-hydroxyapatite (GO-HAP) nanocomposite anticorrosion pigment, by which HAP nanoflakes are induced to in situ grow on the plane of GO sheets. GO-HAP nanocomposite pigment exerts excellent anticorrosion activity. The impedance increases by 754.4% compared with blank epoxy system due to synergistic effect of the formation of chlorapatite and electron collection of graphene oxide.301
