| titleOfInvention | Aqueous compositions of fluorinated surfactants and methods of using the same |
| abstract | Aqueous compositions comprising surfactant represented by a formula selected from the group consisting of: [Rf-(O)t-CHF-(CF2)n-COO-]i Xi+; {[Rf-(O)t-CQH-CF2-O]m-R-COO- }i Xi+; {[Rf-(O)t-CQH-CF2-O]m-R-SO3-)i, Xi+; and [CF3CFH-O-(CF2)p-COO-]i Xi+; 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; X1+ represents a cation having a valence i, wherein i is 1, 2 or 3; t is O or 1; m is 1, 2, or 3; n is O or 1; and p is an integer from 1 to 6. In some aspects, the aqueous composition comprises a non-fluorinated polymer and is essentially free of fluoropolymers. In another aspect, the aqueous composition has a pH of greater than 11. In another aspect, the aqueous composition has a pH of at least 8 and is essentially free of fluorinated olefins. Methods of coating a surface and an article having a surface in contact with the composition are provided. Methods of cleaning a surface, and methods of lowering the surface tension of a liquid having a pH greater than 11 using aqueous compositions comprising the surfactants are also provided. |
