Abstract
Two intrinsic properties of fluorinated tails (F-butyl to F-octyl) were combined in the elaboration of superhydrophobic surfaces by electrochemical polymerization: their promesogenic characteristic and their ability to increase both hydrophobicity and oleophobicity. We report the synthesis and the characterization of pyrrole monomers bearing fluorinated liquid crystalline segments. The electrodeposited corresponding polymer films were characterized by cyclic voltammetry, static and dynamic contact angle measurements, and scanning electron microscopy. Sticky superhydrophobic surfaces were obtained with a F-hexyl or a F-octyl tail. The presence of mesogenic segments improves the surface hydrophobicity and increases the surface roughness, clearly observed with F-butyl and F-hexyl chains.
