Abstract

Due to the predominance diseases such as bone fracture, bone cancer, and osteoporosis Worldwide. There is a developing requirement for synthesizing biomaterials for bone repair or substitute due to the predominance of bone fracture, bone cancer, and osteoporosis. In this study, multi-wall carbon nanotubes (MWCNT) of (0.6%, 1%, 1.4%, 2%) wt.% and High-density polyethylene HDPE (60) wt.% were incorporated into hydroxyapatite (40) wt.% to form biocomposite using hot-press techniques. These samples were characterized by XRD, Field Emission scanning electron microscope (FESEM), Atomic force microscopy (AFM), mechanical properties with tensile strength and hardness test. Homogeneous, better distribution of the fibrous network and microstructure arrangements were among the most prominent characteristics obtained through XRD, FESEM, and AFM examinations. The result showed improved approximately (3.1 times) compared with pure sample (without addition MWCNT) in the tensile test. Also, the microhardness improves approximate 24% compared to pure samples HA/ HDPE. Based on the experimental results, the synthesis HA/ HDPE/MWCNT bio-composites prepared to have excellent characteristics that make them suitable application as a substitute material for bone repair
