  • Publication number: 20250031700
    Abstract: Polyamines are water-soluble polyelectrolytes with the amino groups that can be used to attach the polymers onto functional surfaces of fibrous materials. In addition, polyamines can be readily modified by (super)nucleophilic groups such as (alkyl)aminopyridines that enhance the polymer's ability to promote hydrolysis of organophosphorous chemical warfare agents. Furthermore, attachment of hydantoin moieties augments the number of the imide, amide, or amine groups groups on the polyamine's chain, which provides oxidizing properties to the resulting modified polyamine after halogenation. In one aspect, disclosed herein are polyamines with side chains modified to contain both (4-aminopyridine, APy) and 5-(4-hydroxybenzylidene)hydantoin (HBH) functionalities with enhanced content of the active bromine. Viricidal activity of the APy- and HBH-modified polyallylamine against human coronavirus (type 229E) was tested both in solution and on nylon-cotton fabric.

  • 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.
