THE PREPARATION AND PERFORMANCE OF GRAPHENE/THERMOPLASTIC POLYURETHANE NANOCOMPOSITES

Abstract

Abstract: Graphene oxide (GO) was reduced by a thermal reduction method to prepare reduced graphene oxide (RGO). Nanocomposite films were fabricated for GO/thermoplastic polyurethane (TPU) and RGO/TPU. Furthermore, thermal conductivity, electrical conductivity and mechanical properties of the nanocomposite films were investigated. The results show that GO/TPU nanocomposites have high thermal conductivity and low electrical conductivity, and RGO/TPU nanocomposites have high thermal conductivity and high electrical conductivity as well. Moreover, addition of the GO and RGO can significantly improve the tensile strength and modulus of TPU, respectively.

Key words: graphene, thermoplastic polyurethane, conductivity, mechanical properties
