Abstract: The present disclosure is directed to systems and methods for producing a metal-containing powder useful for additive manufacturing. The metal-containing powder includes a plurality of metal-containing platelets having a defined physical geometry and a defined aspect ratio. The metal platelets may be produced by depositing a metal layer on a substrate that includes one or more recessed or raised surface features. The one or more recessed or raised surface features create a fracture pattern in a metal layer deposited across at least a portion of the one or more surface features. By separating the metal layer from the substrate and fracturing the metal layer along the fracture pattern, a plurality of metal platelets are produced. In some embodiments, a release agent may be disposed between the metal layer and the substrate to facilitate the separation of the metal layer from the substrate.

Abstract: The present disclosure relates to the present disclosure relates to a method of fabricating an aligned polymer containing a bonded substrate and related compositions. The method involved placing a polymer in solution which is capable of alignment wherein the polymer is also bound to a selected substrate. This may then be followed by placing the polymer solution in an electrochemical cell wherein the polymer solution is in contact with at least one electrode and applying an electric field/voltage to the polymer solution and generating a pH gradient wherein the polymer and bonded substrate positions at the isoelectric point of the polymer in solution.
