The investigationresults presented in this article are focused on the influence of the compositionof coatings, which are used for obtaining of membranes, on their oil/water separating ability.To obtainmembranes of a special type of wettability, two compositions were chosen: fluorine-containing coating, which is based on poly(diallyldimethylammonium chloride)/pentadecafluorooctanoic acid and particles of SiO 2 (PDDA/PFOA/SiO 2 ) and coating without fluorine, which is based on hydrolyzed methyltriacetoxysilane.It is found that obtained membranes are hydrophilic, but depending onthe composition of their coating, they areoleophobic to different types of organic liquids.In particular, membranes coated with PDDA/PFOA/SiO 2 possess strong oleophobicity to polar organic liquids of low density -kerosene, while membranes coated by hydrolyzed methyltriacetoxysilane are highly oleophobic to more dense organic liquids -vacuum pump and rapeseed oils.
