Abstract

Ultra high molecular weight polyethylene has been commonly used as a biomaterial for total joint replacements. This article concerns with the characterization of nano composites of ultra high molecular weight polyethylene (UHMWPE) with Mg_0.15Ni_0.15Zn_0.70Fe₂O₃ using analytic techniques such as differential scanning calorimetry (DSC), and thermo gravimetric analysis (TGA). UHMWPE purchased from Sigma Aldrich was used for studies and preparation of nano composites with 1wt% and 2wt% Mg_0.15Ni_0.15Zn_0.70Fe₂O₃ using the ball milling method. The thermal stability of composites with 1 % of Mg_0.15Ni_0.15Zn_0.70Fe₂O₃ contents were less stable compared to pure UHMWPE and UHMWPE composites with 2wt% of nano scale Mg_0.15Ni_0.15Zn_0.70Fe₂O₃. The degree of crystallinity obtained from DSC data was 41%, 40%, and 43% for UHMWPE, UHMWPE+1% of Mg_0.15Ni_0.15Zn_0.70Fe₂O₃, and UHMWPE+2% of Mg_0.15Ni_0.15Zn_0.70Fe₂O₃, respectively. The results of current study are useful while considering the nano composites of UHMWPE with Mg_0.15Ni_0.15Zn_0.70Fe₂O₃ in order to enhance the mechanical strength of UHWMPE for industrial as well as medical applications such as orthopedic implants and bullet proof jackets etc.
