Rapid fabrication and characterization of superhydrophobic tri-dimensional Ni/Al coatings

Superhydrophobic tri-dimensional Ni/Al coatings (3DNACs) with great application value have been successfully fabricated via a simple two-step method combined with hydrogen bubble dynamic template and electrophoretic deposition technique after 1H, 1H, 2H, 2H-perfluorodecyltriethoxysilane treatment. The surface morphologies and chemical compositions were analyzed by FE-SEM, EDS, XRD, AFM and FT-IR in detail. The water contact angle of superhydrophobic 3DNACs surface was as high as 156   ±   2° (>150) much larger than that of unmodified samples. Moreover, the obtained samples exhibited great thermal properties and combustion performance. Thus, the superhydrophobic 3DNACs with prominent exothermic capability turn out to be a promising novel energy in field of mirco/nano energy materials for longer-term storage or transportation, especially in high humid environment.
