摘要

Here we report a simple and cost-effective technical route for constructing superhydrophobic surfaces with excellent abrasion resistance on various substrates. Rough surface structures were fabricated by thermal spray deposition of a variety of inorganic materials, and further surface modification was made by applying a thin layer of polytetrafluoroethylene. Results show that the Al, Cu, or NiCrBSi coatings with the surface roughness of up to 13.8 mu m offer rough surface profile to complement the topographical morphology in micro-ano-scaled sizes, and the hydrophobic molecules facilitate the hydrophobicity. The contact angles of water droplets of 155 with a sliding angle of up to 3.5 degrees on the samples have been achieved. The newly constructed superhydrophobic coatings tolerate strong abrasion, giving clear insight into their long-term functional applications. (C) 2015 Elsevier B.V. All rights reserved.
