Abstract

Technicolor dreamcoat: Spray-on nanoscale coatings are formed by simultaneous spraying of complementary species (e.g., polyanion/polycation, polyelectrolyte/small oligomeric ion, two inorganic salt solutions) against a receiving surface (see picture). The process leads to the formation of ultrathin films, the thicknesses of which are controlled by the spraying time. This general one-step coating method results in optically homogeneous films from a broad choice of functional compounds.
