Recently, electronic and smart devices have been faced on heat dissipation problems. Polyurethane has been known as a polymeric material that has high mechanical strength and has been widely used as adhesive, film, and etc. In order to be used as heat dissipation film for electronics devices, PU/graphene composite materials has been widely studied. In this work, we synthesized PU-RGO composites newly by chemical method to improve both thermal conductivity and mechanical properties. We observed chemical structure, morphology, thermal properties and adhesion strength of PU-RGO composites with various type of chain extender. |
