Textiles with a superhydrophobicity/icephobicity properties could find applications as water resistant apparel**and would generally be useful for any kind of application where textile surfaces are exposed to the**environment. Formation, adhesion, and accumulation of water, snow, frost, glaze, rime, or their mixtures can**cause severe problems for any fabrics. An ice repellent surface is a surface on which the ice adhesion strength**is significantly lowered and where ice accumulation can be easily removed from the surface.It is well known**now that the combination of proper surface roughness and materials with low surface energy is a successful**way to prepare superhydrophobic/icephobic surfaces. However, the low mechanical stability of**superhydrophobic/icephobic surfaces is the bottleneck we are facing in their practical applications.**The objective of this project, with accompanying our partner Chlorophylle, is to develop a new**anti-wet/anti-ice textile surfaces with a dry atmospheric pressure plasma technique including an in-depth**characterization of the resulting superhydrophobic/icephobic fabrics. The plasma system uses a compress**ambient air, and the material processing zone is at the open atmosphere. Therefore, the system meets ideally**industrial production requirements.**In this project, we investigate how to control and optimize the deposition chemistry and the influence of**different operational parameters (discharge power, deposition time, precursor flow rate, substrate-plasma**distance, ...) on thin film properties. The wettability and physico-chemical characterization of developed**surfaces will be studied using water contact angle, X-ray photoelectron spectroscopy (XPS), and SEM analyses.**The ice delayed formation and ice adhesion measurement will be carried out to evaluate the icephobicity of the**new developed coating. Finally, the durability of developed surfaces will be studied against some extreme**environmental condition as different pH solution.
