Aqueous compositions of fluorinated surfactants and methods of using the same

ft2n−ii+ft2m−ii+ft2m3−ii+32p−ii+f 3i+Aqueous compositions comprising surfactant represented by a formula selected from the group consisting of: [R-(O)-CHF-(CF)-COO]X; {[R-(O)-CQH-CF-O]-R-COO}X; {[R-(O)-CQH-CF-O]-R-SO}X; and [CFCFH-O-(CF)-COO]X; wherein Rrepresents 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 CF; R is selected from the group consisting of alkylene and arylene; X 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.
