Fabrication of Cu-CuO-Fe2O3/Fe anti-sticky and superhydrophobic surfaces on iron substrate with mechanical abrasion resistance and corrosion resistance

Abstract

Cu-CuO-Fe2O3/Fe superhydrophobic surfaces (SHSs) have been fabricated successfully on iron substrate via chemical substitution deposition and subsequent annealing treatment. The resulting surfaces exhibit remarkable superhydrophobicity with a water CA of 165 ±2° and a SA of approximately 0° without any organic modification. The surface morphology and chemical compositions were investigated using field emission scanning electron microscopy (FESEM), energy dispersive spectroscopy (EDS), x-ray powder diffraction (XRD) and x-ray photoelectron spectroscopy (XPS), and the surface roughness was analyzed by atomic force microscopy (AFM). The thermal treatment which caused the generation of new chemical substance and the formation of micro-/nano- binary architectures was important for superhydrophobicity, and also enhanced the affinity of iron substrate and the coatings. The annealing temperature and time were further investigated to explain the significance of surface morphology and chemical composition for fabricating the optimal SH samples at appropriate conditions. The resulting SHSs exhibited roll-down and anti-abrasion and anti-corrosion properties, which may have significantly potential value for more applications.
