Synthesis and Characterization of TiO₂Nanoparticles with Polycarbonate and Investigation of its Mechanical Properties

Abstract

In this project, nanocomposite films were prepared with different Titanium dioxide (TiO2) percentages. Properties of polycarbonate (PC) and PC–TiO2 nanocomposite films were studied by X-ray diffraction (XRD) analysis and Fourier transform infrared (FTIR) spectroscopy. The structure of samples was studied by XRD. The mechanical properties of PC–TiO2 nanocomposite films were investigated by conducting tensile tests and hardness measurements. Thermal stability of the nanocomposites was studied by thermogravimetric analysis (TGA) method. The elastic modulus of the composite increased with increasing weight fraction of nanoparticles. The microhardness value increases with increasing TiO2 nanoparticles. The results of tensile testing were in agreement with those of micro-hardness measurements. In addition, TGA curves showed that nanocomposite films have higher resistance to thermal degradation compared to polycarbonate. There are many reports related to the modification of polycarbonate films, but still a systematic study of them is required.

“…A BUEHLER (model 60044 USA) microhardness tester with a mounted microscope was used to conduct Vickers microhardness testing. TGA curves reveal that TiO 2 nanocomposite films have stronger thermal resistance than polycarbonate films, and this resistance appears to grow as the TiO 2 concentration rises [ 139 ].…”
