Abstract
Methods of making functional surfaces, including liquid repellant surfaces that can exhibit selective wetting properties. Methods of forming the functional surfaces can comprise providing a dispersion of nanoparticles; and applying the dispersion to a polymer surface to form a multiplicity of re-entrant structures embedded within and protruding from the polymer surface. The re-entrant structures are formed from aggregates of the nanoparticles. Functional surfaces are prepared by these methods, as well as articles comprising these functional surfaces.
