    • Aqueous compositions comprising surfactant represented by a formula selected from the group consisting of: [Rf—(O)t—CHF—(CF2)n—COO−]iXi+; {[Rf—(O)t—CQH—CF2—O]m—R—COO−}iXi+; {[Rf—(O)t—CQH—CF2—O]m—R—SO3−}iXi+; and [CF3CFH—O—(CF2)p—COO−]iXi+; wherein Rf represents a partially or fully fluorinated aliphatic group optionally interrupted with at least one oxygen atom; Q is selected from the group consisting of F and CF3; R is selected from the group consisting of alkylene and arylene; Xi+ represents a cation having a valence i, wherein i is 1, 2 or 3; t is 0 or 1; m is 1, 2, or 3; n is 0 or 1; and p is an integer from 1 to 6. The aqueous composition comprises a non-fluorinated polymer and is essentially free of fluoropolymers. Methods of coating a surface and an article having a surface in contact with the composition are provided.
    • 包含由选自以下的式的表面活性剂组成的水性组合物:[Rf-(O)t-CHF-(CF 2)n -CO 2 - ] i X i + {[Rf-(O)t-CQH-CF2-O] m -R-COO-} iXi +; {[Rf-(O)t-CQH-CF2-O] m -R-SO3-} iXi +; 和[CF 3 CFH-O-(CF 2)p-COO-] i X i +; 其中Rf表示任选被至少一个氧原子间断的部分或完全氟化的脂族基团; Q选自F和CF 3; R选自亚烷基和亚芳基; Xi +表示具有i价的阳离子,其中i为1,2或3; t为0或1; m为1,2或3; n为0或1; 并且p是1至6的整数。水性组合物包含非氟化聚合物并且基本上不含含氟聚合物。 提供涂覆表面和具有与组合物接触的表面的制品的方法。
