Abstract: A multi-functionalized NPG nanosheet can be used to form a 3D hierarchical multi-functionalized NPG membrane (NPG-pTD membrane) for use in oil/water separation. The NPG-pTD membrane includes a plurality of multi-functionalized NPG nanosheets in a stacked assembly with polyphenolic nanoparticles attached to the NPG nanosheets throughout the membrane. The NPG-pTD membrane can be formed via in-situ polymerization, which is vacuum assisted, such that the phenolic compounds from the multi-functionalized NPG nanosheet form the nanoparticles. Interlayer d-spacing between the adjacent nanosheets in the stacked assembly creates expansive and constricted channels, in addition to nanochannels provided by the pores in the nanosheets, such that the membrane has aquaporin-like properties. The NPG-pTD membrane exhibits high permeability and flux and superior selectivity for effective oil/water separation.
