Recently, graphene and its derivatives have been studied to increase the biological and mechanical properties of CP structures and their results have been satisfactory. Objective: In this study, the main objective is to investigate the physical properties of GO/DCPD powders, which has been synthesized via a simple precipitation method. Material and Methods: Calcium nitrate tetrahydrate and diammonium hydrogen phosphate were used as a precursor for DCPD synthesis. DCPD was precipitated in the presence of graphene oxide. The powders obtained after washing and drying were evaluated. The analysis performed in the sample includes inductively coupled plasma (ICP), Raman Spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction, Energy dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy, Field Emission Scanning Electron Microscope (FE-SEM), and high-resolution TEM. Result: Raman Spectroscopy and XRD results showed that dicalcium phosphate dehydrate formed the hybrid powders along with graphene oxide. DCPD crystallite size was estimated at 138 nm. Microscopic images confirmed the preferred directional growth of DCPD particles. FTIR and XPS results confirmed the emerging bands. ICP and EDS results confirmed the presence of trace elements in the synthesized powders. Conclusion: According to the above, these powders will have a lot of potential for modifying the properties of bone cement.}, keywords = {Tissue engineering,calcium phosphate,graphene oxide,Bone Cement,Precipitation}, url = {https://www.jourtm.com/article_84398.html}, eprint = {https://www.jourtm.com/article_84398_ae42c4727d0630a8799f5c0bc3180559.pdf} }
