The present invention includes a robotic system for the enhanced automation, manipulation, and control of electroprocessing in two or three dimensions. In one embodiment, the system includes a sealed chamber devoid of any electrical or conductive components which would interfere with the electrical field and eventual material fabrication, while still allowing for two-dimensional and three-dimensional robot motion. In certain embodiments, the system of the invention produces materials or scaffolds with complex shapes, including materials with ridges, valleys, curves, and the like, which are difficult or impossible to construct using traditional systems.

A method for providing a metallic coat covering a surface is disclosed, which comprises: (i) applying an electrically conductive two component binder on said surface; (ii) electrostatic spraying a metal powder on the binder applied in step (i); wherein the metal powder comprises metal particles with an average diameter less than 80 micron.

Embodiments described herein relate generally to the production of graphene/polymer compounds. In some embodiments, a method for producing graphene/polymer compounds includes compounding graphene nanoflakes with non-conductive polymer hosts via electrospray coating techniques, taking advantage of the highly electrostatically chargeable properties of graphene to de-agglomerate and further exfoliate the graphene nanoflakes in-situ, and providing uniform and well-dispersed graphene nanoflake coating on various non-conductive polymer hosts, such as polymer fine particles, pellets, fibers, fabrics, non-woven, film, and formed articles. In some embodiments, the deposition of the graphene nanoflakes onto the hosts may be performed in combination with other components, such as but not limited to metal oxides and polymers. The method can be a batch or a continuous process, and is suitable for large scale production of graphene coated materials such as graphene/polymer compound, which can be further processed by, for example, extrusion, compression molding, or injection molding, to yield formed articles.

The present invention has to do with an efficient system for coating and caring engineered wood products (EWP) in general, and the edges of EWPs in particular. An efficient system for coating and curing coatings is provided.

A coating material for producing a coating includes 10 to 70 wt. % of at least one CH acidic compound, 4 to 40 wt. % of at least one vinylogous carbonyl compound, 0.1 to 15 wt. % of at least one latent-basic catalyst, 0.00001 to 10 wt. % of at least one light stabilizer, 0.00001 to 20 wt. % of at least one open time extender, 0.00001 to 20 wt. % of at least one pot life extender, 0.00001 to 70 wt. % of at least one of an inorganic pigment and an organic pigment, and 0.1 to 40 wt. % of at least one corrosion protection agent. Each wt. % of a respective ingredient is based on a total amount of the coating material

A curved substrate with a film includes a substrate having a first main surface, a second main surface and an end surface, and an antiglare film provided on the first main surface. The substrate has a flat portion and a bent portion. A value obtained by dividing a reflected-image diffusibility index value R of the bent portion by the sum of the reflected-image diffusibility index value R of the bent portion and a reflected-image diffusibility index value R of the flat portion is 0.3 or higher and 0.8 or less.

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.

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 method includes steps of: attaching a grounded clip to an insulating workpiece; spraying water-based paint to the workpiece while moving a paint gun from a position where the painting has started in a predetermined direction to form a first band-like painting film; spraying the water-based paint to the workpiece while moving the paint gun to thereby form a second band-like painting film, in which the second band-like painting film is formed in parallel to the first painting film, and a part of the second band-like painting film overlaps the first painting film. An amount of overlap between the first and second painting films is within a range previously determined based on an influence on the water-based paint sprayed when the second painting film is formed that causes the water-based paint sprayed to be attracted to the grounded first painting film.

A system and method for forming a part via additive manufacturing and powder coating the part. The system comprises an additive manufacturing system and a powder coating system. The additive manufacturing system includes a frame, support surface, material reserve, feeder, material applicator, a set of motors, and a processor. The additive manufacturing system produces a part core formed of a non-conductive low melting point material according to a computer aided design. The powder coating system includes a primer applicator, powder coating applicator, and curing apparatus. The material applicator applies a conductive primer to an outer surface of the part core. The conductive primer is then air dried. The powder coating applicator applies an electrostatically charged powder coating to the conductive primer. The curing apparatus then cures the powder coating and conductive primer without the temperature of the core of the part reaching the non-conductive low melting point material melting point.
