Thermal conductivity and diffusion coefficient of polymer blend 80%EP/20%UPE reinforced with sand particles

Abstract

New polymer blend with enhanced properties was prepared from (80 %) epoxy resin (Ep), (20%) unsaturated polyester resin (UPE) as a matrix material. The as-obtained polymer blend was further reinforced by adding Sand particles of particle size (53 μm) with various weight fraction (5, 10, 15, 20 %). Thermal conductivity and sorption measurements are performed in order to determine diffusion coefficient in different chemical solutions (NaOH, HCl) with concentration (0.3N) after immersion for specific period of time (30 days). The obtained results demonstrate that the addition of sand powder to (80%EP/20%UPE) blend leads to an increase of thermal conductivity, with an optimum/minimum diffusion coefficient in (HCl)/(NaOH), respectively.

“…In transient method temperature changes with time, whereas for non‐transient method temperature is constant throughout the time. R.H. Khalaf et al also measured K of EP/UPE polymer blends by using Lees disc method 65 . We adapted same method utilized in our previous study, whole process and setup of lee's disk method was explained in the same literature study 43,66 .…”
