Images of composite membranes, emulsions, and composite-incorporated and composite-coated hydrophobic surfaces prepared using different salts. (a) Macroscopic appearance of composite membranes after emulsions are templated and dried on a surface, (b) microscopic image of emulsions in the wet state, (c) fluorescent microscope images of the composite-incorporated hydrophobic fluid, and (d) SEM images of composite-coated hydrophobic surfaces prepared with different ionic salts, scale bar = 100 μm.
