This work analyzes the anti-icing performance of flat aluminum surfaces coated with widely used alkyl-group based layers of octadecyltrimethoxysilane, fluorinated alkylsilane and stearic acid as they are subjected to repeated icing/deicing cycles. The wetting properties of the samples upon long-term immersion in water are also evaluated. The results demonstrate that smooth aluminum surfaces grafted with alkyl groups are prone to gradual degradation of their hydrophobic and icephobic properties, which is caused by interactions and reactions with both ice and liquid water. This implies that alkyl-group based monolayers on aluminum surfaces are not likely to be durable icephobic coatings unless their durability in contact with ice and/or water is significantly improved.
这项工作分析了涂覆有广泛使用的基于烷基的十八烷基三甲氧基硅烷、氟代烷基硅烷和硬脂酸层的扁平铝表面在经受反复结冰/除冰循环时的抗冰性能。还评估了样品在长期浸入水中后的润湿性。结果表明，接枝有烷基的光滑铝表面容易因其与冰和液态水的相互作用及反应而使其疏水和憎冰性能逐渐退化。这意味着铝表面基于烷基的单分子层不太可能是耐用的憎冰涂层，除非其与冰和/或水接触时的耐久性得到显著改善。
