Abstract
ABSTRACTIn an effort to develop a membrane system with low cost and easy fabrication process for oil/water separation, cellulose nanocrystals (CNC), chitin nanocrystals (ChiNC), and cationic guar gum (CGG) are used to prepare a complex membrane on top of a poly(ethylene terephthalate) (PET) nonwoven fabric via a vacuum filtration method. The interactions among CNC, ChiNC, and CGG complexation are discussed, and the functionalization of the PET nonwoven fabric with these polysaccharide derivatives provides a high rate of water absorption and permeability on applying pressure. The morphology and wettability studies demonstrate that the as‐prepared membrane has a porous structure and exhibits hydrophilic and underwater superoleophobic properties. The results of separation experiments show that the membrane can effectively separate oil/water emulsions with a relatively high flux and rejection ratio. This low‐cost process can easily be scaled up to fabricate complex membranes for oil/water separation. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47947.
