Thermal Properties of UPE-PMMA Blend Reinforced by ZnO Nanoparticles

Abstract

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.
