Abstract

Patterned surfaces: The fabrication of patterned superomniphobic–superomniphilic surfaces is reported. Such patterned surfaces are expected to be useful in developing well-defined microreactors for liquid-phase reactions, significantly enhancing heat transfer during condensation and boiling of various low-surface-tension liquids, and in fabricating precisely tailored arrays of polymers and microparticles of different sizes and shapes.
