Fluorinated siufactants have been evaluated for paper uses since die early 1960s [13, 95, 96]. Perfiuorooctyl sulfonamido ethanol-based phosphates were the first substances used to provide grease repellence to food contact papers [97-99]. Fluorotelomer thiol-based phosphates and polymers followed [100-102]. Since paper fibers and phosphate-based fluorinated surfactants are both anionic, cationic bridge molecules need to be used in order to ensure the electrostatic adsorption of the surfactant onto the paper fiber. These surfactants are added to paper through the wet end press where cellulosic fibers are mixed with paper additives before entering the paper forming table of a paper machine. This treatment provides excellent...
