Graphene (reduced graphene oxide-rgo) or graphene oxide (go)/poly(vinyl alcohol) (pva) nanocomposite membranes were fabricated by solution-casting method. The effects of additive content on the pervaporation (pv) performance of membranes were investigated. The membrane characterizations were performed by fourier-transform infrared spectroscopy, differential scanning calorimetry, x-ray diffraction, and transmission electron microscope. The characterized results indicated that thermal stability and pv performance of nanocomposite membranes were improved compared to the neat pva membrane. In comparison with neat pva, rgo/pva membrane showed a high selectivity of 51.2, but low permeate flux of 0.056 kg.m^-2h^-1); and go/pva exhibited an acceptable selectivity of 34.9, however equivalent permeate flux of 0.120 kg.m^-2h^-1
