Abstract
A method for simultaneous additive manufacturing and thickness-limited, electrospray deposition may include forming an electrically conductive target via additive manufacturing and exposing the electrically conductive target to an incident spray comprising a thermo-responsive polymer solution, in the presence of an electric field. The electrically conductive target may have a surface temperature, the thermo-responsive polymer solution may have a solution temperature, and the thermo-responsive polymer solution may include a non-conductive polymer. The method may further include allowing the solution temperature to deviate toward the surface temperature to a deposited temperature at which the non-conductive polymer is immobile. The method may further include 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.
