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 Mg0.15Ni0.15Zn0.70Fe2O3 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% Mg0.15Ni0.15Zn0.70Fe2O3 using the ball milling method. The thermal stability of composites with 1 % of Mg0.15Ni0.15Zn0.70Fe2O3 contents were less stable compared to pure UHMWPE and UHMWPE composites with 2wt% of nano scale Mg0.15Ni0.15Zn0.70Fe2O3. The degree of crystallinity obtained from DSC data was 41%, 40%, and 43% for UHMWPE, UHMWPE+1% of Mg0.15Ni0.15Zn0.70Fe2O3, and UHMWPE+2% of Mg0.15Ni0.15Zn0.70Fe2O3, respectively. The results of current study are useful while considering the nano composites of UHMWPE with Mg0.15Ni0.15Zn0.70Fe2O3 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.
