Nanohybrid graphene oxide (GO)/polyimide (PI) mixed matrix membranes (MMMs) were prepared by dispersing GO into PI through wet phase inversion method. The structure of GO/PI MMMs was characterized by using XRD, FT-IR and XPS. FESEM was used to analyze the morphology of the GO/PI MMMs. The hydrophilicity of the GO/PI MMMs was determined by static water contact angles. The performances of the GO/PI MMMs were evaluated for desalination of seawater through pervaporation.The GO/PI MMMs display excellent water permeability and salt rejection for desalination of different concentrations of seawater. At 90 C, the GO/PI MMMs exhibit a high water flux (36.1 kg m À2 h À1) and a high salt rejection (99.9%). Further, the GO/PI MMM displays a high stability for seawater desalination.This high separation performance combined with high stability and facile fabrication route recommend the developed GO/PI MMMs as a promising candidate for desalination of seawater.

“…The permeance of water increased with increasing the temperature similar to other hydrophilic membranes [47]. For solvent dehydration, the enhanced permeant diffusivity of water (dominated by the loosened structure and the weakened coupling effect between water and ethanol [48]), was usually sufficient to compensate for the decrease in the permeant solubility [24]. By contrast, higher temperature suppressed the adsorption of ethanol on the membrane surface and inhibited the diffusion of ethanol along with water molecules because of the weakened coupling effect between water and ethanol [49], thus decreased the ethanol permeance.…”

“…The functional groups' of GO enhances the interface interaction with PEI polymer [29,30]. The GO contains polar groups which can easily interact with water molecules and it increases the hydrophilicity of the membrane and diffusion rate of permeate side [31,32]. The water selectivity is improved via the presence of the GO functional groups [33][34][35][36].…”

In the present investigation, laboratory synthesized graphene oxide (GO) as a nano-filler was used in polyetherimide (PEI) flat-sheet membranes (PM). The PEI flat-sheet membrane was fabricated through a dry-thermal treatment (DTT) method. The effects of fabrication method were investigated on polyetherimide-GO membrane prepared by dry-thermal treatment (PMDTT). The morphological structure was investigated via different characterization; Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), contact angle measurement and Raman spectra. The results indicated that, the hybrid PMDTT membrane displayed reasonably better pervaporation separation performance in comparison to neat PMDTT membranes. The concentrations of water at the permeate side of hybrid and neat PMDTT membrane were 99.3 and 90.9 wt.%, respectively. Hybrid membranes showed a 78.3% enhanced permeation rate. Enhancement of pervaporation property of hybrid PMDTT membrane could be ascribed mainly due to the presence of graphene oxide in the dense top layer. Overall, the blending of graphene oxide in hybrid PMDTT membranes could be a promising approach for enhancing the pervaporation properties of the membranes.
