In this study, a superhydrophobic nickel surface that is highly robust against repetitive rubbing is presented. We implanted carbon nanotubes (CNTs) to protect the surfaces from contacts. We show that the CNTs implanted in nickel do not easily detach from the surface and maintain superhydrophobicity despite harsh rubbing (40 kPa, 600 cycles) by 800 grit sandpaper; by contrast, surfaces prepared by typical nanofabrication methods are visibly damaged and lose superhydrophobicity after such treatment. The CNT-implanted nickel surfaces developed in this study are the most robust among nanostructured surfaces reported up to date.
