Nanostructures, Surface wetting
Removal of contaminated oil or organic spills on water, or water droplets in oils
The creation of large-scale free-standing structures for practical applications
The invention includes a simple and rapid approach to controlling surface wetting, based on self-assembled free-standing structures of ultralong manganese oxide nanowires. The nanowire assemblies, composed of micro- and nanoporous structures that span multiple length scales, exhibit a remarkably superhydrophilic response. When coated with a thin layer of hydrophobic molecules, the nanowire assemblies become superhydrophobic. The assemblies of this invention are useful in various applications, including removal of organics or hydrophobic materials, and waterproofing application.
