A facile modification of a PVDF membrane using CaCO3 inorganic particles via a layer-by-layer self-assembly process for efficient oil/water separation.
A polyurethane (PU) sponge with excellent oil/water separation property has been successfully prepared by modifying with octadecyltrichlorosilane (OTS) self-assemblies.
Stainless steel felt modified with hierarchically structured coatings and hydrophobicity can achieve a removal efficiency of greater than 99% for oil-in-water emulsion separation.
