In this study, graphene oxide and creatine phosphate disodium acted as dual template and was employed to synthesize graphene oxide (GO)/hydroxyapatite (HA) hybrids as drug carriers. In the rapid preparation of GO/HA hybrids, creatine phosphate disodium salt (CPDS) severed as a phosphorus source and graphene oxide acted as a template in aqueous solution. The effects of the reaction temperature, time and pH value of the aqueous solution on the morphology of the product were investigated. The result showed that the hydrolysis of CPDS under hydro thermal condition played an important role in the formation of hierarchical hollow GO/HA hybrids. The GO nano sheets provided reactive sites for the binding of HA nanoparticles and absorbing ibuprofen (IBU) molecules. The GO/HA hybrids had ideal sustained drug-release behavior. It indicated that the prepared GO/HA hybrids may be promising materials for applications in biomedical area. (C) 2016 Elsevier B.V. All rights reserved.
