Synthesis of polyurethanes through UV-curing process contributes to the environmental protection by removing the hazardous organic solvents. At first, UV-curable urethane acrylate (UA) ZrO2 nanocomposites with different weight percentages of ZrO2 were synthesized and then thermal conductivity of the nanocomposites was measured by infrared thermography. Infrared thermography results showed that adding ZrO2 nanoparticles to the urethane acrylate matrix increased surface reflection coefficient and decreased thermal conductivity in the urethane nanocomposites. Consequently, urethane acrylate ZrO2 nanocomposites (3 and 5 wt%) acted as strong thermal insulators.
