Effect of adding nanoparticles from zirconia or alumina on some mechanical properties of the ternary polymer blend

Due to the importance of polypropylene and its use in wide applications, So, in this research will be study effect of adding two types of nanoparticles (Zirconia and Alumina) as reinforcing materials with different percentages of weight are (0.3%, 0.5%, 0.7%) to improve mechanical properties of the ternary polymer blend which based on polypropylene material, according to the proportions of the components ((94%PP: 1%(PP-g-MA): 5%UHMWPE): X% (ZrO₂ or Al₂O₃)), were prepared by melting technique using double screw extruder. Moreover, in this research to improve adhesive force and increase compatibility between reinforcing nanoparticles materials and with polymeric blend components, it was used polypropylene grafted malic anhydrated with ratio 1% (PP-g-MA). The results illustrated that the effect of adding 0.3% ratio of ZrO₂ nanoparticles to the ternary polymer blend was gave better mechanical properties (tensile strength, impact strength, fracture toughness) compared with adding of the Al₂O₃ with the same ratios and to the same group of the ternary polymer blend, and the As well as, that it was observed that the maximum values of these properties arrived to 32.25 MPa, 41 kJ/m², 7.69 MPa√m, respectively.
