英文摘要	We fabricated a novel thin-film composite (TFC) membrane by integrating sulfonated graphene oxides (SGO) in its active layer. This novel membrane holds a great promise in forward osmosis (FO). The SGO was effectively synthesized from graphene oxide (GO), as it possesses a high hydrophilic nature, which in turn imparts enhanced desalination capacity for TFC-FO membranes. The structure and properties of TFC, GO-incorporated TFC membranes (GTFC) and SGO-incorporated TFC membranes (STFC) were characterized by attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), scanning electron microscopy (SEM), and atomic force microscopy (AFM), and SGO incorporation was proven to be successful. Osmotic performance tests showed that STFC-FO membranes achieved higher water flux and reverse salt flux selectivity than GTFC-FO and TFC-FO membranes. The best STFC-FO membrane exhibited the water flux of 27.14 LMH with the specific reverse salt flux of 0.13 g/L. The SGO incorporation onto membrane also contributed to its decreased fouling propensity.
