In　this　study,　the　inter-layer　spacing　between　graphene　oxide　(GO)　layers　were　tuned　with　solvent　green　(SG)　to　enhance　the　nanofiltration　performance　of　the　laminar　GO　membranes.　GO　nanosheets　were　firstly　modified　by　SG　through　the　strong　pi-pi　stacking　interactions.　The　SG@GO　nanocomposites　were　then　assembled　onto　the　surface　of　tubular　ceramic　substrate　through　immersion　method.　The　morphologies　and　structures　of　the　resulting　SG@GO　composite　membranes　were　characterized　by　scanning　electron　microscope　(SEM),　energy　dispersive　X-ray　spectrometer　(EDX),　X-ray　diffraction　(XRD),　and　Fourier　transform　infrared　(FTIR).　The　composite　membrane　was　used　for　removing　dye　molecules　(Eriochrome　black　T)　from　water.　It　was　found　from　the　results　that　the　SG@GO　composite　membranes　showed　a　flux　of　330　L　m(-2)　h(-1)　MPa-1,　which　was　nearly　6-fold　enhancement　compared　with　that　of　the　pristine　GO　membrane　(56　L　m(-2)　h(-1)　MPa-1),　without　sacrificing　the　dye　rejection.　Therefore,　this　strategy　may　provide　a　facile　approach　to　tune　the　inter-layer　spacing　of　GO　laminates　for　efficient　molecular　separation.
