Abstract
A liquid composition comprising at least one bisphosphonic compound bearing at least one partially fluorinated, perfluorinated (PF) or perfluorpolether (PFPE) group. The bisphosphonic compound is dissolved in at least one non-flammable fluorinated solvent or in a mixture of non-flammable fluorinated solvents. A method for increasing the lipophobic or hydrophobic properties of a surface is also disclosed, wherein a liquid composition comprising at least one bisphosphonic compound bearing at least one partially fluorinated, perfluorinated (PF) or perfluorpolether (PFPE) group is applied to the surface. The method may include preliminary oxidation of the surface, if necessary; contacting the surface with the liquid composition until the bisphosphonic compound contained therein is assembled in a layer coating the surface; and drying the surface thus coated.
