Effect of aspect ratio of graphene oxide on properties of poly (vinyl alcohol) nanocomposites

In this study, the effect of aspect ratio of graphene oxide (GO) on the properties of poly (vinyl alcohol) (PVA) nanocomposites were investigated. The PVA/GO nanocomposites were prepared by a simple solution casting method. GO with 3 different lateral sizes, 0.5, 1.5 and 3 µm were used. The higher t...
