Perfluorinated poly(dimethylsiloxane) via the covalent attachment of perfluoroalkylsilanes on the oxidized surface: Effects on zeta-potential values

► Poly(dimethylsiloxane) is surface-modified with perfluorinated siloxanes. ► Surfaces show increases in zeta potential with increasing perfluoroalkyl chain length. ► Perfluorinated surfaces support electro-osmotic flow across a wide pH range. ► Perfluorinated surfaces are resistant to the diffusion of PDMS oligomers.
