Preparation of stable Ni3S2 superhydrophobic surface via hydrothermal reaction

Abstract

Superhydrophobic materials have become a hot issue in the field of surface and interface science because of their excellent properties and broad application prospects. In this paper, ${\mathrm{Ni}}_{3} \mathrm{S}_{2}$ micro-nanostructure was prepared on the nickel foam via the hydrothermal reaction. The superhydrophobic surface was obtained after modifying with tetradecanoic acid and the optimal minimum time was 12 h. Functional tests of the superhydrophobic surface revealed that the prepared superhydrophobic surface had distinct self-cleaning property and high temperature resistance.
