| Popis: | International audience; This work aims at developing polymer surfaces with enhanced hydrophobic behaviour by controlling both thesurface chemistry and the surface structure. The chemical modification is given via the elaboration of polymersblends by incorporation of own-synthetized tailored fluorinated additives (FA) in commercial polystyrene and thephysical approach is based on micro/nano-structuration of polymers surface. Different films containing variouscontent of fluorine based on commercial polystyrene (PS) and FA were elaborated by solvent casting method. Thenano-structuration of polymers surface was replicated from a Nickel insert using hot embossing technique withoptimized processing conditions including, polymer/mold interfaces, micro/nano-textures, temperature andpressure. The impact of FA on both the wettability properties and the replication efficiency was evaluated, bywater/polymer static contact angle and quantification of replication rate, respectively. It was evidenced that the useof this tailored additive, even at low percentages, associated with the structuration of the PS surface improvessignificantly the hydrophobicity of polystyrene and the robustness of the replication process. |
