1. A method of preparing a treated article, said method comprising the steps of:
providing a slurry comprising fibers; combining the slurry and a first fluorinated composition to form a mixture; forming at least one sheet from the mixture; and applying a second fluorinated composition on at least one surface of the at least one sheet to prepare the treated article; wherein the first fluorinated composition is further defined as an anionic fluorinated composition comprising a fluorinated polymer and wherein the second fluorinated composition is further defined as an anionic fluorinated composition comprising a fluorinated polymer, wherein a ratio of the amount of the fluorinated polymer in the first fluorinated composition to the amount of the fluorinated polymer in the second fluorinated composition is from 1:4 to 1:7.
