A new approach to the synthesis of functional thin films: hierarchical synthesis of CaCO3 thin films and their transformation into patterned metal thin films.
A patterned metal thin film was synthesized based on a new approach that allows the formation of thin films with complex shape, hierarchical organization, and controlled size under ambient conditions in an aqueous environment. By using a general coating system, a CaCO(3) thin film was transformed into a patterned metal thin film with functional properties, such as adhesion and hydrophobicity. Atomic force microscopy (AFM) and surface-profiling experiments were carried out to measure the adhesion between the probe tip and the substrate and to determine the film thickness. Separation of the patterned ceramic thin film occurred very easily by means of sputtering and chemical treatment with an acidic solution.
