Poly fluorine-containing siloxane coatings having improved hydrophobic and oleophobic properties and solutions for creating such coatings are provided. In some embodiments, the coating includes a polymer having a plurality of Si&#x2014;O&#x2014;Si linkages; and at least two fluorine-containing moieties, each attached to at least one of the Si&#x2014;O&#x2014;Si linkages. Each fluorine-containing moiety independently includes a linking portion attached to a silicon of one of the Si&#x2014;O&#x2014;Si linkages, wherein the linking portion is of a formula selected from the group consisting of: &#x2014;[CH]&#x2014; where a is an integer from 1 to 10 and &#x2014;[CH]CONH[CH]&#x2014; where b and c are independently an integer from 0 to 10. Each fluorine-containing moiety also independently includes a fluorinated portion attached to the linking portion, wherein the fluorinated portion is selected from a fluorinated-alkyl group having 1-10 carbon atoms and a perfluoro-ether containing organic group.
