  • Patent number: 10804031
    Abstract: This invention relates to a magnetic paint composition for application to a substrate. Such substrate can be a wall, partition, building materials, and the like; fabric, web, paper, and the like; or other objects capable of receiving a film-forming composition which would benefit from having a magnetic or magnetizable surface. This invention also relates to fabric, web, paper, and the like substrates coated with a magnetic film-forming composition. Such fabric, web, paper, and the like substrates may be panels of various shapes and sizes and may include an adhesive on a surface of the substrate such that the panel may be removably positioned on a surface. Preferably, the coated panel can be removed and repositioned without damaging the panel or the underlying surface.

  • Patent number: 10646829
    Abstract: A filtration membrane coating comprising a hydrophilic polymer, a surfactant, and one or more charged compounds, each containing one or more sulfonate functionalities and one or more linkable functionalities selected from the group consisting of amine, monochlorotriazine, and dichlorotriazine. The hydrophilic polymer and surfactant form a thin primer layer which is also superhydrophilic. The primer layer improves flux, and enables improved adhesion of the one or more charged compounds, which form a charged dye layer on top of the primer layer when enhances rejection of charged divalent ions. The coating can be applied while the membrane is packaged in its final form, such as in a spiral wound or other configuration.

  • Patent number: 10573443
    Abstract: Disclosed is a simplified process for producing magnetic polymer particles. The process comprises: (a) providing a composition having a liquid monomer which is radical polymerizable, a radical initiator soluble in the monomer, a steric stabilizer, and a ferrofluid comprising surfactant-coated colloidal magnetic particles in a carrier fluid which is miscible with the monomer; (b) preparing an emulsion from a polar solvent which is immiscible with the monomer, and the composition of step (a); (c) adding seed polymer particles to the emulsion, mixing to form a seeded emulsion, and incubating the seeded emulsion, thereby swelling the seed polymer particles; and (d) activating the radical initiator and polymerizing the monomer in the swollen seed polymer particles; thereby producing the magnetic polymer particles. The process forms monodisperse magnetic particles. The particles are characterized by a uniform distribution of magnetic material, and an absence of magnetite bleeding.
