Preparation of nanocomposite by reinforcing the polymer matrix with nanoceramics for load bearing bone implants applications. The polymer matrix of choice was Poly-lactic acid (PLA). The nanoceramic, that is nanohydroxyaptite (NHA) was synthesised prior to mixing with graphene platelets (GNP) forming nanohybrid filler (NHA-GNP). Then, the NHA-GNP was used to reinforce the PLA matrix. The mechanical, thermal, dynamic mechanical properties as well as surface morphology of the fractured samples were analysed. Finally, recommendation on the biocompatibility of the nanocomposite was made based on the in-vitro analysis conducted.
