Popis:	The study addresses the relationship between the omniphobic properties of coatings based on polymer matrices doped with liquid lubricants (Slippery Liquid-Infused Porous Surfaces, SLIPS) and the degree of swelling of the matrices in the lubricant. A method for fabrication of matrices based on poly(perfluoroalkyl methacrylates) impregnated with fluorinated oils with different lubricant contents by one-stage synthesis in supercritical (SC) CO2 is proposed. The dependence of the contact angle hysteresis and the sliding angle on the degree of swelling was studied for water and saturated hydrocarbon droplets. The lubricant content in the matrices was determined by thermogravimetric analysis and ellipsometry.
