Nowadays graphene based composites were developed due to their unique structure and excellent properties. Present study involves the preparation of graphene grafted chitosan and hydroxyapatite (GgCH) composite through solution casting method for biomedical applications. The prepared composite was characterised by FTIR, TGA, DSC XRD and SEM analysis. The formation of GgCH composite was confirmed by FTIR and XRD studies through the shifting of peak values from Chitosan to GgCH composite due to strong interaction between the compounds (HAP, chitosan and Graphene). Thermal stability of the sample was analysed by TGA-DSC curves. The SEM images were recorded and compared with pure graphene.
