Abstract
Self-limiting electrospray compositions including a non-charge-dissipative component and/or a charge-dissipative component. Self-limiting electrospray composition including a plurality of charge-dissipative components and excluding a non-charge-dissipative component. Methods for forming layers of self-limiting thickness. Methods for determining a conductivity of a material. Methods for repairing a flaw in a layer on a surface of an object.
Claims5
A method of thickness-limited, electrospray deposition comprising:
- exposing an electrically conductive target to an incident spray comprising a thermo-responsive polymer solution, in the presence of an electric field,
- wherein the electrically conductive target has a surface temperature,
- wherein the thermo-responsive polymer solution comprises a non-conductive polymer,
- wherein the thermo-responsive polymer solution has a solution temperature;
- allowing the solution temperature to deviate toward the surface temperature to a deposited temperature at which the non-conductive polymer is immobile;
- and
- allowing the non-conductive polymer to accumulate on the electrically conductive target to form a layer, having a thickness sufficient to repulse the incident spray.
