| Abstract | ||
| In this research, nanocomposites of thermoplastic polymer (Poly Methyl Methacrylate, PMMA) and nanoparticles reinforcement (Zirconium Oxides, ZrO2) have been fabricated by solution casting method. ZrO2/PMMA nanocomposites have been prepared with different weight fraction (0, 1, 1.5, 2.5, 3 and 5 wt%) of ZrO2 particles with help of chloroform as a solvent. Some physical properties, such as : mechanical properties (tensile strength, hardness), thermal properties (glass transition temperature, thermal conductivity) of prepared samples as a function of weight fraction(concentration) of ZrO2 in nanocomposites have been investigated. Mechanical properties showed that the tensile strength and hardness increases with increasing ZrO2 concentration, and the hardness reached their maximum value at 1 wt% of ZrO2. Thermal properties results shown increase in glass transition temperature and thermal conductivity as ZrO2 weight fraction increase, and the thermal conductivity reached highest value at 1 wt% of ZrO2. | ||
