A system that incorporates teachings of the present disclosure may include, for example, an apparatus having a plurality of applicators, each applicator with an ingress opening to receive a liquid, and an egress opening to release the liquid, and a conductor positioned in a conduit of each of the plurality of applicators, the conductor and the conduit having dimensions to cause a surface tension of the liquid to prevent a constant flow of the liquid from the egress opening. Each conductor of the plurality of applicators can be coupled to one of one or more power sources operable to apply a charge to the liquid to overcome the surface tension and form at the egress opening of each applicator a plurality of jet sprays of the liquid applicable on a substrate to form a thin film. Additional embodiments are disclosed.

A method for producing a thin film or nanoparticle deposit includes the step of providing a working liquid, movement of the working liquid at a liquid surface prevented by surface tension. The method also includes the steps of supplying an electric charge having a first polarity to the working liquid at the liquid surface to overcome surface tension at the liquid surface to produce a first plurality of charged nanodrops and directing the first plurality of charged nanodrops against a substrate surface. The method further includes the steps of supplying an electric charge having a second polarity to the working liquid at the liquid surface, the second polarity being opposite to the first polarity, to overcome surface tension at the liquid surface to produce a second plurality of charged nanodrops, and directing the second plurality of charged nanodrops against the substrate surface. The method additionally includes the step of alternating between supplying the electric charge having the first polarity and supplying the electric charge having the second polarity to the working liquid at the liquid surface. An apparatus for producing a thin film or nanoparticle deposit includes an apparatus for supplying a working liquid, surface tension preventing movement of the working liquid from the apparatus for supplying a working fluid at a liquid surface, an apparatus for supplying an electric charge to the working liquid at the liquid surface to overcome the surface tension to produce a stream of nanodrops, and an apparatus for supplying electric charge of alternating polarity to the apparatus for supplying the electric charge to the working liquid at the liquid surface.
摘要:
A method and apparatus for producing nanodrops which are liquid drops with diameters less than one micron and producing therefrom solid nanoparticles and uniform and patterned film deposits. A liquid precursor is placed in an open ended tube within which is a solid electrically conductive needle which protrudes beyond the open end of the tube. Surface tension of the liquid at the tube end prevents the liquid from flowing from the tube. Mutually repulsive electric charges are injected into the liquid through the needle, causing the surface tension to be overcome to produce a plurality of liquid jets which break up into nanodrops.

The subject disclosure provides a method for applying dissimilar electrical charges to portions of a plurality of applicators by way of a conductor included in a conduit of each applicator. The method further includes causing each applicator to generate one or more jet sprays of a liquid received by each applicator for application of a material on a substrate, where one or more portions of the material on the substrate have one or more net charges associated with the dissimilar electrical charges applied to the portions of the plurality of applicators, where the conductor of each applicator is a sleeve positioned in the applicator, and where a diameter of the sleeve results in one of an outer surface of the sleeve contacting a surface of the conduit, or the outer surface of the sleeve having a separation from the surface of the conduit of the applicator. Additional embodiments are disclosed.
