Deposition and tuning of nanostructured hydrocarbon deposits: From superhydrophobic to superhydrophilic and back

Résumé

Carbonaceous fluorine free nanoparticles synthesized in a low temperature acetylene discharge are used in a first step for the production of (super)hydrophobic coatings. In a second step, the influence of different plasma and UV induced functionalizations on the wetting characteristics of these materials is investigated. The experiments show that the superhydrophobic surfaces can be turned continuously and reversibly into hydrophilic (superhydrophilic) surfaces by means of the different treatment methods. The reversibility of these processes is studied in a third step. It is shown that the changes of the surface which are induced by the plasma treatment can be undone by means of EUV irradiation. The switchability of the surface due to external stimuli can be easily used for the controlled production of patterned surfaces. This is demonstrated by means of one simple example.
