This paper investigated the effect of zirconium oxide (ZrO2) and titanium oxide (TiO2) on the morphology and mechanical properties of poly (methyl methacrylate) (PMMA) blends. Composites of PMMA (5/95 wt%) with ZrO2 and TiO2 were prepared by modified sol-gel reaction and then the composites were integrated by compression. The dispersion of ZrO2 and TiO2 nanoparticles in the polymer matrix was investigated after deposition as thin films, using optical microscope. It was studied also the transparency and the band gap of thin films of the individual compounds and of the mixed zirconia composites. It was observed that the dispersion of ZrO2 nanoparticles was relatively good with low ZrO2 content, but the aggregates of ZrO2 particles in a polymer matrix increased with increasing the ZrO2 content. The Vickers hardness test on PMMA and ZrO2-PMMA showed that the value of hardness increases as the percentage of ZrO2 increases. The adding of zirconia nanoparticles showed that the composites can be used in fabrication of different application as metal protection, dental materials, abrasion resistant materials, transparent protection due to the hardness tests.
