20_01b/2008Inside Front Cover: Superhydrophobic Surfaces Generated from Water-Borne Dispersions of Hierarchically Assembled Nanoparticles Coated with a Reversibly Switchable Shell (Adv. Mater. 1/2008)

On p. 200, Sergiy Minko and co-workers report on the fabrication of a superhydrophobic coating from aqueous dispersions of hybrid responsive nanoparticles with no application of surfactants and organic solvents. A suspension of the particles forms a textured hydrophilic coating upon casting. Heating above the glass transition temperature of polystyrene, or treatment in acidic water, resulted in backward and forward switching between the superhydrophobic and the hydrophilic material, respectively.
