Surface micro- and nanostructure of SNF-coated Al samples. (a) Optical surface roughness maps of bare Al substrate, NaOH etched Al substrate and fluorinated-SNF-coated Al (F). (b–e) SEM micrographs of: b bare Al substrate, (c) NaOH etched Al substrate, and (d, e) sample F. (f) SEM micrograph of sample F, with its EDX maps of (g) Si and (h) F. (j) EDX spectra of bare Al substrate, NaOH etched Al substrate and SNF-coated Al before and after fluorination.
