Plasmachemical Functionalization of Solid Surfaces with Low Surface Energy Perfluorocarbon Chains

Pulsed plasma polymerization of precursors containing long perfluoroalkyl chains can lead to the formation of structurally well-defined low surface energy films. Greater chemical selectivity and faster deposition rates are found for monomers containing carbon−carbon double bonds compared to their saturated analogues. Critical surface tension values ( γ c ) as low as 1.5 mN m - 1 have been achieved, which corresponds to exceptional hydrophobic and oleophobic liquid repellency behavior.
