Abstract
As the elderly population increases, the need for bone loss treatments is increasing. Vital substances used in such treatments are required to continue for a longer period and work more effectively. The particularly important biological material is poly methyl methacrylate (PMMA) bone cement, which is widely used in damaged bone replacement surgery. So, this study focused on the role of added some nanoparticles consist of zirconia (ZrO2), and magnesia (MgO) on the binary polymeric blend (Acrylic bone cement: 15% PMMA) for a bone scaffold. Where, ZrO2 and MgO nanoparticle was added with selected weight percentages (0, 0.5, 1, 1.5 and 2 wt.%), which were added to the polymer blend matrix. Some mechanical properties were studied including the tensile strength and young modulus for all the prepared samples. The chemical bonding of nanoparticles and synthetic binary polymeric blend composites was evaluated by Fourier Transform Infrared (FTIR) spectroscopy. Tensile strength and young modulus of binary polymeric blend reinforced with 1.5 wt.% ZrO2, and 1 wt.% MgO, significantly increased. The surface morphology of the fracture surface of tensile specimens was examined by Scanning electron microscope (SEM). The SEM images confirmed that the homogenous distribution of nanoparticles (ZrO2, and MgO) within the polymeric blend matrix.
Highlights
Bones play a key role in our bodies, allowing daily tasks to be performed
The results demonstrated that there is an increase in the tensile strength with an increase in wt.% of ZrO2

Summary
Bones play a key role in our bodies, allowing daily tasks to be performed They are important for storing minerals and producing red blood cells. A polymer mixture is a component of a material category where two or more polymers are combined to form a fresh material with distinct physical characteristics. Polymer blending is a technological way to provide materials with a complete set of desired special properties at the lowest price, such as a combination of toughness and strength, and solvent resistance. ZrO2 has a range of useful characteristics, including great toughness and mechanical strength, resistance to abrasion and corrosion, and biocompatibility. The main objective of this study was to improve the mechanical properties of the polymeric blend that’s reinforced with nanoparticle (ZrO2, and MgO) according to the standards of bone tissue engineering
