摘要

本研究的目的是证明在（羟基磷灰石/高密度聚乙烯）生物复合材料中添加多壁碳纳米管（MWCNTs）纳米颗粒的效果。在本研究中，通过热压技术制备了具有不同百分比（MWCNTs）的样品。研究了HA/HDPE/MWCNTs生物复合材料的形态特征、表面粗糙度和热性能。内部纤维网络的良好均匀分布和微观结构排列是通过FE-SEM和AFM检查获得的最突出的特征之一。结晶度表明，与纯样品（未添加MWCNT）相比，（MWCNTs）添加剂增强了约（35%）。基于所获得的实验结果，所提出的生物复合材料样品的制备表现出优异的特性，使其成为一种有前途的生物医学应用材料，可作为骨等硬组织重建的替代材料。

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

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.
