HA/HDPE Reinforced with MWCNTs for Bone Reconstruction and Replacement Application

Abstract

The objective of this study is to demonstrate how the effect of adding multi-walled carbon nanotubes (MWCNTs) nanoparticles to the (Hydroxyapatite /High-density polyethylene) bio-composites. In this investigation, the samples with various percentages of (MWCNTs) were fabricated by a hot-press technique. The morphological characteristics, roughness of the surface and thermal properties of the bio-composite samples (HA/HDPE/MWCNTs) were investigated. The excellent homo-geneous distribution of the internal fibrous network and microstructure arrangements were among the most prominent characteristics obtained through FE-SEM and AFM examinations. The degree of crystallinity showed that the (MWCNTs) additives enhance by an increase of approximately (35%), compared with pure sample (without addition MWCNTs). Based on the experimental results obtained, the fabrication of the presented bio-composites sample exhibited the excellent characteristics that make them promising material for biomedical application as a substitute material for hard tissue likes bone reconstruction.

A review: In vivo studies of bioceramics as bone substitute materials

“…[ 7 ] There is a developing need for synthesizing biomaterials for bone healing or replacement due to osteoporosis, bone cancer, and bone fracture. [ 8 ] Tissue engineering is regarded as an alternative method for repairing bone defects. In standard tissue engineering techniques, a template that works as a bridging material is called a scaffold.…”
