“…The durability of the surface was also studied by exposing the fabricated sample in air for 8 months, showing excellent long-term stability at these conditions. Li et al 26 produced SHP aluminum surface by chemical etching and cyclic assembly using hydrochloric acid, phytic acid, cerium (III) chloride or ferric chloride and 1H,1H,2H,2H-perfluorooctyltriethoxysilane (FAS13). Such SHP surfaces demonstrated thermal stability up to 200 °C and chemical stability up to 16 h, immersed in 3.5% sodium chloride solution.…”

Superhydrophobic (SHP) and oleophobic aluminum surfaces have been prepared through the combination of a scalable chemical microtexturing process and surface functionalization with long-chained polyfluoroalkyl moieties. The effect of an anodic layer on the microtextured surface has been assessed considering surface morphology, superhydrophobicity, surface mechanical properties and corrosion protection enhancement. The surface functionalization with polyfluoroalkyl moieties has been tackled in two different ways: (i) grafting of the polyfluoroalkyl moieties and (ii) deposition of a thin hybrid coating with low content of polyfluoroalkyl-containing compound. Aluminum surfaces showing high durability in salt spray environments, which maintain SHP and oleophobic properties at least up to 2016 h have been attained. Applications for this kind of surfaces range from easy-to-clean surfaces to anti-icing or anti-condensation functionalities that could be of interest for several sectors.
