  • Electric field “Z” direction alignment of nanoparticles in polymer solutions
    Patent number: 10710281
    Abstract: A method of preparing a polymer film having an oriented dispersed material includes casting a multi-layer polymer solution having a first polymer solution layer and a second polymer solution layer where the second polymer solution layer is at least partially immiscible with the first polymer solution layer. The method further includes passing the multi-layer polymer solution through an electric field application zone, to thereby induce orientation of the dispersed material. A multi-layer polymer film can then be formed by drying the solvent from the multi-layer polymer solution. An apparatus for preparing polymer films includes a top electrode made from a flexible metal mesh coated with a non-stick, non-conductive coating.
