Abstract
Embedding nanomaterials in thin film composite membranes to overcome the dynamic balance between salt rejection and permeability has become a research hotspot. Apparently, the filling positions of nanomaterials in membranes have a significant influence on membrane properties. In this work, GO@CS core-shell nanomaterials was firstly successfully synthesized, with good hydrophilicity and fast water transmission channels. Then the influences of addition amounts and loading positions of GO@CS on membrane performance were explored. Results demonstrated that embedding GO@CS with 0.01 wt% in the polyamide layer could give full play to the advantages of core-shell nanomaterials and improve the water flux and salt rejection (water flux increased by 115%, salt rejection increased to 99.10%), as well as the performance stability. Compared with TFN membrane with GO@CS embedded between the polyamide layer and supporting layer, the TFN membrane with GO@CS embedded in the polyamide layer could make full use of advantages provided by GO@CS that fast water transmission channels and the interlayer spacing assisting in salt rejection. This work provided guidances for the effect of nanomaterials with hierarchical pores embedding position on membrane performance.
