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.

具有超疏水/憎冰特性的纺织品可以作为防水服装**，并且通常适用于纺织品表面暴露于**环境的任何类型的应用。水、雪、霜、釉、霜或它们的混合物的形成、粘附和积累会对任何织物造成严重的问题。防冰表面是一种表面，在这种表面上冰的粘附强度**显着降低，冰的积聚可以很容易地从表面去除。众所周知，适当的表面粗糙度和低表面能材料的结合是制备超疏水/憎冰表面的成功方法。然而，**超疏水/疏冰表面机械稳定性低是其实际应用中面临的瓶颈。**该项目的目标是与我们的合作伙伴叶绿素一起，利用干大气压等离子体技术开发一种新的抗湿/抗冰纺织品表面，包括对所得到的超疏水/憎冰织物的深入表征。等离子体系统采用压缩环境空气，材料加工区处于开放气氛。因此，该系统理想地满足了**工业生产的要求。在这个项目中，我们研究了如何控制和优化沉积化学，以及不同操作参数（放电功率、沉积时间、前驱体流量、衬底-等离子体距离等）对薄膜性能的影响。利用水接触角、x射线光电子能谱（XPS）和扫描电镜（SEM）分析研究开发**表面的润湿性和物理化学特征。**将进行冰延迟形成和冰粘附测量来评估**新开发涂层的憎冰性。最后，将研究开发表面在不同pH溶液等极端环境条件下的耐久性。
