Nanocomposite films of PVA/PAA/SrTiO3 NPs were fabricated for electronic and optic approaches using a low cost method. The AC electrical characteristics of PVA/PAA/SrTiO3 films were investigated. The results showed that the dielectric constant of polymeric blend increases from 5.39 to 7.25, and the dielectric loss increases from 1 to 30. While, the electrical conductivity increases from 5.00E−11 to 2.00E−9 with increasing the SrTiO3 NPs content. Also, the dielectric constant of polymeric blend increased from 5.39 to 8.04, and the dielectric loss increased from 0.377 to 1.21. While, the electrical conductivity increased from 2.09E−11 to 6.70E−11 with increasing the frequency.

In this study, thermal analysis properties (Heat Transfer) have been studied for UPE-PMMA polymer blend reinforced with x-ZnO where x is (0wt%, 1wt%, 2wt%, 3wt%, 4wt% and 5wt %). Ultrasonic dispersion technique used to prepare the nanocomposites specimens follow with cold casting technique using Teflon molds at standard conditions. C - Thermosensor (TC i) technique was used to measure the heat transfer properties such as; (thermal conductivity, thermal effusivity, thermal diffusivity, heat capacity and thermal resistance). Results show that the values of conductivity, effusivity and diffusivity are increased by succession of weight percentage of fillers. While a heat capacity and thermal resistance results show that the values are decreased progressively by succession of weight percentage of fillers. Scanning electron microscopy was employed to aid interpretation results of thermal analyzer and to show the distribution of nanoparticles in polymer matrix.

Films of PVA/PAA/SrTiO3 nanostructures were prepared for flexible optoelectronic devices. Studying the optical characteristics of PVA/PAA/SrTiO3 films were tested. The results showed the improving of the optical characteristics of (PVA/PAA) mixtures by the increase in SrTiO3 NPs content. Also, results showed the energy gap of PVA/PAA mixtures decreased from to with adding of SrTiO3 NPs. Finally, the results indicated to the PVA/PAA/SrTiO3 nanostructures may be used in various optoelectronic devices.

In this study, the MgTiO3 ceramic system was used in a dry mixing method with 2: 1 mol and was reinforced to white acrylic powder used in dental applications to form a mixture of 1%, 2%, 3%, 4% and 5% of ceramic powder. The ultrasound technique was used to disperse the powder and distribute it homogeneously in the chloroform solution for one hour and then mixed it with acrylic powder in the same technique for half an hour. The tests were done for the samples made using industrial saliva with bacteria. Calculate the rate of wear using Pin on disc method. The results were interpreted based on the resulting images from the scanning electron microscope and the density of the prepared samples.
