Mechanical behavior of nano-scaled graphene oxide reinforced high-density polymer ethylene for orthopedic implants

Abstract

The application of bio-composite materials is in trends recently, for both commercials as well as the scientific community. In order to achieve inherent strength and efficient performance, biocompatible materials are often modified. This is done with an aim to replace organic cells/tissues if required. In recent times, the polymer composites are used as an alternative for body implants than traditional metal-based components. Cost inefficiency and corrosion resistivity are the major problems associated with metallic implants. Polymer composite offers similar advantages as that of metallic based components. Moreover, it can also be molded in the requisite shape, are cost-efficient, have a high corrosion rate, and less weight. This paper aims to fabricate a biopolymer nanocomposite with efficient fatigue, mechanical, and wear properties, which is suitable for human implant applications. The studies evident effective mechanical and efficient tribological properties, demonstrated by implants for knee and hip replacement. The graphene oxide employed in the experiment study retains antibiotic properties and is also tends to be bio-compatible. Nano graphene oxide, along with high-density polyethylene at varying wt.% of 0.5-2.5%, was reinforced, which resulted in better tribological outcomes. This composite material is environment friendly and has the potential to be used for numerous applications.
