  • Patent number: 10867719
    Abstract: Disclosed are compositions of electroactive polymers (EAPs) having improved performance stability. In the EAP compositions, a cross-linked polymer is deposited onto the surface of the EAP by vapor-deposition methods. Upon contact with an aqueous solution (e.g., an aqueous electrolyte solution), the vapor-deposited polymeric network becomes a hydrogel that encapsulates the EAPs. By modulating precursors and vapor deposition conditions, the mesh size of the resultant hydrogel coatings can be controlled to accommodate the key species that interact with the EAPs.

  • Patent number: 8945393
    Abstract: Method for oil removal. The method includes adding a magnetizable material, with or without appropriately selected surfactants, of order micron (having no net magnetization) or nanometer size to magnetize the oil or water phase by either making a ferrofluid, magnetorheological fluid, a magnetic Pickering emulsion (oil in water or water in oil emulsion), or any other process to magnetize either oil or water phases. The magnetized fluid is separated from the non-magnetic phase using novel or existing magnetic separation techniques or by permanent magnets or electromagnets thereby separating oil and water phases. The magnetized particles are separated from the magnetized phase using novel or existing magnetic separation techniques to recover and reuse the particles. The two magnetic separation steps can be repeated to further increase recovery efficiency of the liquid phases and the magnetizable particles reused in this continuous process.

  • Publication number: 20130343969
    Abstract: Extraction method for recovering metals. Phosphoric acid is contacted with an extractant suspension of solid particulate material comprising a para- or ferromagnetic material core surrounded by an outer shell of a chelating polymer whereby a metal is the solution is adsorbed on the chelating polymer, thereby removing it from the phosphoric acid solution. The metal-containing solid particulate material is magnetically separated from the solution and the metal is stripped from the solid particulate material for reuse.

  • Publication number: 20110174720
    Abstract: Described is the application of layer-by-layer (LbL) electrostatic assembly techniques to electrospun nanofibers in order to fabricate novel, breathable electrospun fiber-based chemical and biological detoxifying protective fabrics and filters. The combination of layer-by-layer electrostatic assembly and electrospinning technique allows one to take advantage of high specific surface area, light weight and breathability of electrospun fiber mats while simultaneously providing the versatility to incorporate different functional polyelectrolytes to achieve multifunctional coatings for both chemical and biological protection together. The functionalized fiber mats can be incorporated into breathable chemical and biological protective fabrics, filters and masks. In addition, LbL electrostatic coating of porous non-woven materials provides the versatility to generate multifunctional polymer-based membrane materials for other applications.

  • Patent number: 7795041
    Abstract: The present invention relates to multi-polymer-coated magnetic nanoclusters, aqueous magnetic fluids comprising same, and methods of their use in separation procedures. The multi-polymer-coated magnetic nanoclusters comprise a super paramagnetic core, with a first polymer attached thereto, which does not render the first polymer-super paramagnetic particle complex colloidally stable, and a second polymer attached thereto, which stabilizes the complex of multi-polymer-coated magnetic nanoparticles. Methods of use comprise methods of separation, including separation of expressed protein from cells and viruses expressing the same.
