Abstract

A method for the direct electrodeposition of globular nano-hydroxyapatite (nHAp) onto reduced graphene oxide (RGO) is presented and a model for the specific growth preference is discussed. Results show that the carboxyl (carboxylic acid)/carboxylate functional groups attached directly to the RGO after oxygen plasma treatment were essential to accelerate the OH- formation and the deposition of globular nHAp crystals. High resolution scanning electron microscopy, energy dispersive X-ray and X-ray diffraction showed that homogeneous, highly crystalline, stoichiometric nHAp crystals, with preferential growth in the (002) plane direction, were formed without any thermal treatment. The nHAp/RGO composites were shown to be an appropriate surface for mesenchymal stem cell adhesion with active formation of membrane projections. (AU)
