Abstract
A superhydrophilic thin film is formed on a metal surface of a boiler vessel to alter the wettability and roughness of the surface, which, in turn, changes the boiling behavior at the surface. The superhydrophilic film is formed by depositing a layer of a first ionic species on the surface from a solution. A second ionic species having a charge opposite to the that of the first ionic species is then deposited from solution onto the surface to produce a bilayer of the first ionic species and the oppositely charged second ionic species. The depositions are then repeated to form a plurality of bilayers, on top of the preceding bilayer. The bilayers are then heated, leaving the second ionic species on the metal surface to form a superhydrophilic film.
