Robust superhydrophobic diamond microspheres for no-loss transport of corrosive liquid microdroplets

Abstract

Superhydrophobic surfaces usually lose their characteristics when exposed to a corrosive environment. To solve this issue, we synthesized superhydrophobic diamond microspheres by microwave-plasma-assisted chemical vapor deposition. Commercial epoxy glue was used to bond the microspheres to various substrates. The thus-synthesized composite films exhibited robust superhydrophobicity and an ultrahigh adhesive force.
