The accretion of ice and pollution can seriously damage exposed structures. Ice accumulation on outdoor surfaces in cold climate regions leads to hazardous road conditions, damage to power transmission equipment, and the perturbation of rail transportation systems. Ice accretion also accelerates the deterioration of outdoor structures. This project aims to develop a coating that would provide aluminum alloy surfaces with icephobic and easy-clean properties. This novel product would be based on a polyurethane acrylate (PU-acrylate) coating developed by Nanophyll that has both hydrophobic and anti-corrosion properties. This coating has shown good flexibility when used in various settings including the transportation, construction, and decoration sectors where there are challenges related to the removal of unwanted or accidental stains on aluminum structures. This new coating would target several areas where ice accumulation on aluminum surfaces is problematic, including construction, transportation, automotive, aerospace, and agricultural settings. The central objective of this project is to incorporate surface functionalized micro- and nanoparticles into a PU-acrylate coating to create a micro-nanotextured surface that fosters icephobic and self-cleaning properties. The type, size, and dispersal of micro-nanoparticles within the polymer matrix will be optimized to achieve a truly superhydrophobic and easy-clean coating. Furthermore, we will test the resistance of the coating to harsh environmental conditions; a durable coating significantly reduces operation and maintenance costs related to the coated structures. The accumulation of ice and pollution on coatings, however, reduces their performance and durability. As such, we will ensure that the developed easy to clean coating is also icephobic so as to prolong its resistance and efficacy on aluminum surfaces.

积冰和污染会严重损坏裸露的结构。寒冷气候地区室外表面积冰会导致危险的路况、电力传输设备的损坏以及轨道交通系统的扰动。积冰还会加速室外结构的恶化。该项目旨在开发一种涂层，为铝合金表面提供疏冰和易于清洁的特性。该新型产品基于 Nanophyll 开发的聚氨酯丙烯酸酯 (PU-丙烯酸酯) 涂层，具有疏水性和防腐性能。该涂层在运输、建筑和装饰等各种环境中使用时表现出良好的灵活性，这些领域在去除铝结构上不需要或意外的污渍方面存在挑战。这种新涂层将针对铝表面积冰问题的几个领域，包括建筑、运输、汽车、航空航天和农业环境。该项目的中心目标是将表面功能化的微米颗粒和纳米颗粒融入 PU 丙烯酸酯涂层中，以创建具有疏冰和自清洁特性的微纳米纹理表面。聚合物基质内微纳米颗粒的类型、尺寸和分散将被优化，以实现真正的超疏水且易于清洁的涂层。此外，我们还会测试涂层对恶劣环境条件的抵抗力；耐用的涂层显着降低了与涂层结构相关的操作和维护成本。然而，冰和污染物在涂层上的积累会降低其性能和耐用性。因此，我们将确保开发的易清洁涂层也具有疏冰性，以延长其在铝表面的耐受性和功效。
