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

具有超疏水/憎冰性能的纺织品可以用作防水服装**，并且通常适用于纺织品表面暴露在**环境中的任何类型的应用。水、雪、霜、釉、雾气或它们的混合物的形成、粘合和积累会**对任何织物造成严重的问题。拒冰表面是一种表面，在这种表面上，冰的粘合强度会显著降低，积冰很容易从表面上清除。众所周知，将适当的表面粗糙度与低表面能材料相结合，是制备超疏水/疏水表面的成功方法。然而，超疏水/疏水表面较低的机械稳定性是我们在实际应用中面临的瓶颈。**本项目的目标是与我们的合作伙伴Challelle一起，开发一种新的**抗湿/抗冰纺织品表面，该技术采用干燥大气压等离子体技术，包括对所得到的超疏水/疏水织物进行深入**表征。等离子系统使用压缩**环境空气，材料加工区在开放的大气中。因此，该系统能够很好地满足**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**不同的操作参数(放电功率、沉积时间、前驱体流量、基片-等离子体**距离等)的影响。关于薄膜的特性。利用水接触角、X-射线光电子能谱(XPS)和扫描电子显微镜(SEM)分析研究了涂层表面的润湿性和物理化学特性。**将通过延迟结冰和附着力测量来评估新开发的涂层**的疏冰性。最后，将研究显影表面在不同pH溶液等极端**环境条件下的耐久性。

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.
