Abstract
Thin films of copolymers of 1,1-dihydroperfluoroheptyl methacrylate (FHMA) and methyl methacrylate (MMA) were investigated with respect to both their molecular and macroscopic surface properties. Introduction of FHMA entities in copolymer decreases the surface energy to a large extent. Angle resolved X-ray photoelectron spectroscopy (XPS) measurements show an increased average fluorine concentration in a surface layer thickness of a few nanometers, when compared to the fluorine concentration in the bulk. Static LEIS experiments, which selectively probe the outermost atomic layer, show an even stronger enrichment of fluorine atoms.
