采用化学腐蚀、浸涂和氟硅改性等简单工艺，制备了稳定的具有双重几何结构的超疏水铝合金表面。酸蚀和纳米二氧化硅浸渍20min的Al表面具有最好的超疏水性，其水接触角(WCas)为>；157°，水滑动角(SAS)为<；1°。与疏水和亲水铝表面相比，超疏水表面表现出优异的防雾、防霜和延缓结冰性能。此外，经过11次磁带测试和120厘米磨损(在0.8kpa的压力下)，所制备的表面的超疏水性在机械上是持久的。纳米二氧化硅颗粒、氟硅树脂和铝表面之间强烈的界面相互作用使其具有优异的耐磨性。该方法为制备大面积超疏水铝表面提供了一条简便、低成本、稳定的工艺路线。
The stable superhydrophobic aluminum alloy surface with dual geometric architectures was prepared by a combination of simple processes of chemical etching, dip-coating, and modification of fluorosilicone. The Al surface with 20 min of acid etching and nanosilica dip-coating has the best superhydrophobicity, which showed water contact angles (WCAs) of >157° and water sliding angles (SAs) of <1°. The superhydrophobic surface showed excellent antifogging, antifrosting, and delayed icing performances, compared to hydrophobic and hydrophilic Al surfaces. Furthermore, the superhydrophobicity of as-prepared surfaces is mechanically durable after 11 tape tests and 120 cm wear (under a pressure of 0.8 kPa). The strong interfacial interactions among the SiO2 nanoparticles, fluorosilicone-modified polyester resin, and the Al surface contributed to superior abrasion resistance. This method could provide a facile, low-cost, and stable route to fabricate a large-area superhydrophobic Al surface for application in vario...
