Superhydrophobic bagasse paper was successfully engineered by facile spray coating with a zeolitic imidazolate framework composite modified by 3,3,3-trifluoropropyltrimethoxysilane(FAS)and used as a filter membrane with special wettability for oil/water *** characteristics such as surface morphology,surface moieties,roughness,and wettability were *** addition of FAS decreased the apparent surface energy between solid surfaces and liquids with a polar contribution of surface free energy as low as 0 mN m−*** formation of the FAS layer was confirmed by transmission electron microscopy and X-ray photoelectron spectroscopy core-level ***-dimensional surface topography revealed an increase in the spray coating cycle that enhanced the hydrophobicity of the coated *** results confirmed that not only microstructures but also the presence of functional groups with low surface energy(such as FAS)can promote surface *** spray-coated paper with FAS/ZIF in the presence of a small amount of nanocellulose provided a superhydrophobic surface after the first spray *** separation efficiency was up to 85%and was slightly affected by oil ***,this can be used as a filter membrane for water-in-oil *** the present work,simple spray-coated paper is a promising candidate material for gravity-driven oil/water separation and water repellent coating.
