摘要/Abstract

摘要： 采用热还原的方法由氧化石墨烯(GO)制备得到还原石墨烯(RGO),并将两种石墨烯与热塑性聚氨酯(TPU)复合制得纳米复合材料薄膜。进而考察了两种纳米复合材料薄膜的导电、导热及力学性能。结果表明: 在TPU中加入GO能够得到高导热、低导电的纳米复合材料,而加入RGO则得到高导热、高导电的纳米复合材料;同时,GO和RGO的加入,均能显著提高TPU 的拉伸强度和模量。

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
