摘要：In this study, UV-curable urethane acrylate UA synthesized and then characterized by FTIR and HNMR. For better dispersion of nanoparticles in polymeric matrix, nano Al2O3 was modified by silane coupling agent and then its nanocomposites were prepared. The characteristics of synthesized nanocomposites were analyzed by TGA, DMA and infrared thermography. The results signify that adding nano Al2O3 to UA matrix leads to improvement of thermal stability and viscoelastic properties of the nanocomposite. Infrared thermography analysis shows that adding Al2O3 to UA causes the surface reflection coefficient to increase and the heat transfer of UA nanocomposites to reduce. Therefor one could point that UA/Al2O3 3 and 5 wt is a thermal barrier as a heat insulator.
