Plasma polymerisation is a well-established technique for chemically modifying material surfaces and conferring functional effects. For example, radio frequency plasma discharges containing simple fluorinated gases and vapours are widely known to confer high levels of water-repellency (hydrophobicity) to textiles and other materials. However, the level of oil-repellency (oleophobicity) that these treatments confer is very much less than that attainable from conventional "wet' fluoropolymer textile finishes. In this paper, we now report that pulsed electrical discharges containing perfluoroalkylated monomers afford oil-and water-repellent textile finishes whose performance characteristics equal, and in some cases surpass those of conventional fabric treatments.
