In this study, we investigated the effect of graphene based materials such graphene oxide (GO), reduced graphene oxide (rGO), and exfoliated graphene flakes (GF) on thermal mechanical and surface properties of thermoplastic polyurethane (TPU) nanocomposites. Graphene based materials with TPU nanocomposites studied excellent mechanical properties compared to pristine TPU film at low loading using universal testing machine (UTM). Also, the thermal stability of the nanocomposites as examined by thermogravimetric analysis (TGA) to describe the influence of graphene nanofillers on TPU films. Contact angle study revealed that the rGO and GF filled nanocomposites were becoming more hydrophobic whereas GO filled nanocomposites films showed the opposite trend. Our work will provide a guide to design TPU films with graphene based material nanofillers to obtain higher mechanical and more stable thermal properties. |
