Polydimethylsiloxane (PDMS)/carbon nanotube nanocomposite-based coatings are prepared and their surface properŽties are characterized by contact angle measurements and Atomic Force Microscopy. The addition of a tiny amount of multiwall carbon nanotubes (0.1 wt.% MWCNTs) within the polymeric matrix leads to dramatic changes in the wettability and the surface morphology of the material, which take place during immersion in demineralised water. We attribute these phenomena to deep modifications of the organization and mobility of the polysiloxane chains due to the strong affinity between the studied MWCNTs and PDMS. These results provide fundamental insights for the preparation and the use of a novel class of silicone-based coatings, e.g., in antifouling applications.
