Development of a water repellent/anti-icing polyester fabric via atmospheric plasma jet polymerization

具有超疏水性/疏冰性性质的纺织品可以用作防水服装 **，并且通常可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、粘附和积聚会对任何织物造成严重的问题。拒冰表面是指表面上的冰附着强度 ** 显著降低，并且可以很容易地从表面上去除冰积聚的表面。现在众所周知，适当的表面粗糙度和低表面能材料的组合是制备超疏水/疏冰表面的成功方法。然而，** 超疏水/疏冰表面的低机械稳定性是我们在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Chlorophylle一起开发一种新的抗湿/防冰纺织品表面，采用干燥大气压等离子体技术，包括对所得超疏水/疏冰织物的深入表征。等离子体系统使用压缩的环境空气，并且材料处理区处于开放的大气中。因此，该系统理想地满足 ** 工业生产要求。**在这个项目中，我们研究如何控制和优化沉积化学和 ** 不同的操作参数（放电功率，沉积时间，前体流速，基板等离子体 ** 距离，.）的影响。对薄膜性能的影响。将使用水接触角、X射线光电子能谱（XPS）和SEM分析来研究开发的 ** 表面的润湿性和物理化学特性。**将进行冰延迟形成和冰附着力测量以评估新开发的涂层的疏冰性。最后，将研究开发的表面在一些极端环境条件下的耐久性，如不同pH值的溶液。

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.
