A method of forming a material structure from structural units contained within a liquid solution in a spray head is described. The liquid solution includes a solvent and a solute, the solute comprising a plurality of the structural units, the structural units including monomer units, oligomer units, or combinations thereof. The method comprises forming droplets of the liquid solution including the structural units, and spraying the droplets on a substrate, thereby substantially increasing the reactivity of the structural units within the droplets relative to the structural units within the liquid solution in the spray head. The increase in reactivity can result from the droplets containing an excess of a particular ion, the ion excess resulting from a voltage applied to conductive walls of the device which dispenses the droplets. The material structure is then formed on the substrate from the more highly reactive structural units within the droplets.

An electrostatic painting device capable of reducing any AC or electromagnetic emissions when the device is powered on is provided. The emissions affect electronic components present during painting of various objects or even when the device is powered on. The electromagnetic induction into the conductive circuit elements in turn induces voltages and currents, which potentially harm the micro-electronic circuits. One such device includes a choke between a fluid tip and a high voltage source of the device to reduce these emissions. The voltage source may include at least one capacitor which supplies the AC emissions representing electromagnetic emissions risk during the discharge of paint from the device. The choke connected to the voltage source substantially reduces the emissions involved during the paint discharge, while allowing the discharge of electrons, thereby imparting negative DC charge to the paint and the workpiece, and preventing damage to electronic circuits during the process.

Control method and apparatus for a manual spray gun includes display that is disposed on the spray gun and that provides information to an operator about one or more coating operation parameters. An auxiliary trigger may be used that enables an operator to makes selections of one or more coating operation parameters. The display and auxiliary trigger together permit an operator to make selections without having to divert attention or field of view away from the spray gun or the coating area, especially during a coating operation.
