Abstract
Methods for forming thin, pinhole-free conformal metal layers on both conducting and non-conducting surfaces, where the morphology and properties of the metal layers are tuned to meet desired parameters by adjusting the concentration of ionic liquids during the deposition process. The formed metal films contain tunable properties for solar and electronic use and provide specific advantages for non-conducting surfaces, which are otherwise unsuitable for electroplating without the presence of the formed metal films. The disclosed methods do not require the presence of a voltage or external electric field but form the metal films through an electroless technique using electrostatic interactions between negatively charged nanoparticles. In addition, the disclosed methods are compatible with solution phase processing and eliminate the need to transfer the surfaces into a vacuum chamber for a chemical or physical vapor deposition to form a metal layer.
