Superhydrophobic surfaces are attractive as self-cleaning protective coatings in harsh environments with extreme temperatures and pH levels. Hexagonal phase boron nitride (h-BN) films promising due to their extraordinary chemical thermal stability. However, high surface energy makes them hydrophilic thus not applicable water repelling coatings. Our recent discovery on the superhydrophobicity of nanotubes (BNNTs) is contradicting fact that BN materials would be hydrophobic. To resolve this...
