Abstract：

In this study, solvent green (SG) were utilized to modify graphene oxide nanosheets and then SG@GO/PDDA multilayer membranes were fabricated from the as-prepared SG@GO composite via layer-by-layer self-assembly. The preparation of SG@GO was confirmed by TEM, AFM, FTIR and XPS. The results showed that the thickness of GO nanosheets were increased from 2.2 nm to 2.7 nm due to the deposition of SG molecules. The regular alternation of Zeta potential on the surface indicated the successful assembly between SG@GO and PDDA. This could also be proved by the intensity increase of GO characteristic peak on the XRD curves. Then the organic solvent nanofiltration performance of SG@GO/PDDA membrane was studied. The optimized flux and dye retention for methyl blue/methanol solution could respectively reach 50 L/(m2?h?MPa) and 95.2% when the concentration of SG is 1.5 g/L, assembly layer is 3.5. Besides, the obtained SG@GO/PDDA membrane showed desirable stability which could be demonstrated by the 400-min continuous nanofiltration test.
