  • Method of producing uniform polymer beads by vibration jetting with superhydrophobic membrane
    Patent number: 10526710
    Abstract: Spheroidal polymer beads having a uniform size are prepared by polymerizing uniformly sized monomer droplets formed by dispersing a polymerizable monomer phase over double-walled cylindrical cross-flow membrane into an suspension phase. A shear force is provided at a point of egression of the polymerizable monomer phase into the suspension phase, the direction of shear substantially perpendicular to the direction of egression of the monomer phase. The membrane is metallic and includes a superhydrophobic coating.
    Type: Grant

  • Method of producing uniform polymer beads of various sizes
    Patent number: 9415530
    Abstract: Speriodal polymer beads having a uniform size are prepared by polymerizing uniformly sized monomer droplets formed by dispersing a polymerizable monomer phase over a cross-flow membrane into an aqueous phase. A shear force is provided at a point of egression of the polymerizable monomer phase into the aqueous phase, the direction of shear substantially perpendicular to the direction of egression of the monomer phase. The polymer beads can be employed in applications where beads having uniform diameters of 10 to 180 ?m are useful.

  • Filtering a dispersed phase (e.g. oil) from a continuous liquid (e.g. water) of a dispersion
    Publication number: 20090211991
    Abstract: Filtering a dispersed phase (e.g. oil) from a continuous liquid (e.g. water) of a dispersion a filter, for filtering a dispersed phase from a continuous liquid of a dispersion, the filter including a substrate having a plurality of apertures each extending directly through the substrate between a first surface and a second surface and a layer of material applied over at least a portion of the first surface, wherein the material rejects the continuous liquid to a greater extent than the dispersed liquid.
