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