Abstract

After bone implant, short-term complications can lead to a complicated approach to recovery, requiring surgical correction associated with additive risks, such as deep infection and double fracture. The development of synthesized biomaterials for bone replacement or repair, as well as the prevalence of osteoporosis, bone fracture, and bone cancer, is therefore of significant importance. This work aims to demonstrate the effect of adding multi-walled carbon nanotube (MWCNTs) to the (PMMA/ZrO2–CaO) bio-composites to fabricate a new hybrid biocomposite system for bone recovery and replacement applications. Four groups of composite samples were produced PMMA/(0, 5, 10, 15, 20)% weights of ZrO2–CaO and adding (0, .1, 0.25, 0.5, 1)% weights of (MWCNTs) to each group. X-ray powder diffraction (XRD), surface topography by field emission scanning electron microscopy (FE-SEM), and fracture strength tests were performed to evaluate the samples’ properties. A number of the most significant char...
