Abstract [en]

Ultra high molecular weight polyethylene has been commonly used as a biomaterial for total joint replacements. This thesis concerns with the characterization of nano composites of ultra high molecular weight polyethylene (UHMWPE) with Mg0.15Ni0.15Zn0.70Fe2O3 using various analytic techniques such as fourier transform-infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC), and thermo gravimetric analysis (TGA). An accelerating aging of three different samples, two commercial and one laboratory grade UHMWPE purchased from Sigma Aldrich was done to study  the thermal stability of UHMWPE, and the results were checked with FTIR spectroscopy. The FTIR data revealed that UHWMPE purchased from Sigma Aldrich had the highest thermal stability. Therefore, UHMWPE purchased from Sigma Aldrich was used for further studies and preparation of nano composites with 1wt% and 2wt% Mg0.15Ni0.15Zn0.70Fe2O3 using the ball milling method. FTIR data show significant alterations as far as material degradation and crosslinking is concerned. The absorbance in the region 1650-1850 cm-1 and 3000-3700 cm-1 significantly increases due to the enhance of CH2 bending to stretching ratio with the incorporation of Mg0.15Ni0.15Zn0.70Fe2O3. As far as thermal stability is concerned, 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.
