Nonuniform Coating Patents (Class 427/256)
  • Patent number: 11685109
    Abstract: In the formation of a solid object by progressively adding extruded materials to a workpiece, a mechanism is disclosed for transposing the paths by which two or more extrusion nozzles travel to deposit materials. Paralleling a surface contour of the object being formed, the paths for two or more substantially continuous extruded traces are directed in complementary fashion to cause a first extrusion trace to form the object surface while a second extrusion trace is deposited behind the first trace. At another position along the surface contour, the paths of the extruded traces may cross over one another to allow the second extruded trace to define the object surface. Where the first and second traces have a different color or visual appearance, the disclosed mechanism enables fine graphic features to efficiently be integrated into the surface of the object being formed.

  • Patent number: 11669009
    Abstract: A method for fabricating patterns on a flexible substrate in a roll-to-roll configuration. Drops of a monomer diluted in a solvent are dispensed on a substrate, where the drops spontaneously spread and merge with one another to form a liquid resist formulation. The solvent is evaporated (e.g., blanket evaporation) from the liquid resist formulation followed by selective multi-component resist film evaporation resulting in a non-uniform and substantially continuous film on the substrate. The gap between the film on the substrate and a template is closed such that the film fills the features of the template. After cross-linking the film to polymerize the film, the template is separated from the substrate thereby leaving the polymerized film on the substrate.

  • Patent number: 11149154
    Abstract: A simple spray coating process can be utilized to create epoxy/HNT nanocomposites with vertically aligned nanotubes. Important mechanical properties such as modulus and hardness values can be optimized and enhanced by controlling the level of nanotube dispersion during processing and the final orientation of the nanotubes. Thus, a technologically relevant processing scheme can be used to fabricate HNT nanocomposites with a high level of control over nanotube alignment and the resulting mechanical properties.
