    摘要： Filtration media having germicidal for use in filtering particles and deactivating, removing and/or destroying microorganisms from a feed liquid passing through the media. The filtration media includes an effective amount of at least one germicidal agent associated to monomers polmerized and chemically grafted and covalently bonded to the surface of the media. The germicidal filter media is prepared by contacting the media with a grafting solution comprising one or more monomers, a catalyst, a surface agent, a curign agent, at least one graft initiator, and at least on germicide and subsequently curing the media at an elevated temperature to chemically graft the polmerizable monomers onto a surface of the media and associate at least one germicide thereto. Filter media suitable for use in the present invention include ceramic spheroids, hollow glass spheres, polmeric type meida, thermoset coated glass spheres, and crystalline microporous materials, such as zeolites. The germicidal filter media is effective for deactivating, destroying and/or removing from a feed liquid, such as water, escherichia coli, salmonella choleraesuis, staphylococcus, aspergsillus, klebisiella, listeria, clostridium, rotavirus, cysts and other microorganisms. Moreover, the filter media can be used repeatedly without a significant decrease in its germicidal effectiveness.

    摘要： Filtration media having germicidal properties for use in filtering particles and deactivating, removing and/or destroying microorganisms from a feed liquid passing therethrough. The filtration media includes an effective amount of a germicidal chemically grafted and covalently bonded to a surface of the media. The germicidal grafted filter media is prepared by contacting the media with a grafting solution comprising an anionic monomer, a catalyst, a graft initiator and a germicide and subsequently curing tile media at an elevated temperature to chemically graft a polymerized salt of the polymerizable anionic monomer and the cationic germicide onto a surface of the media. Filter media suitable for use in the present invention include ceramic spheroids, hollow glass spheres, polymeric type media and thermoset coated glass spheres. The germicidal grafted filter media is effective for deactivating, destroying and/or removing from a feed liquid, such as water, escherichia coli, salmonella choleraesuis, staphylococcus, aspergsillus, klebisiella, listeria clostridium, rotavirus, cysts and other microorganisms. Moreover, the filter media can be used repeatedly without a decrease in its germicidal effectiveness.

    摘要： A method of grafting a conductive, tenacious, and protective coating on a metallic substrate. The metallic substrate, such as steel, aluminum, iron, platinum, silver, nickel, gold, cobalt, copper, copper alloys, or combinations thereof, is contacted with a composition having: (i) one or more polymerizable monomers having at least two functionalities; (ii) one or more graft initiators containing nickel ion in an amount effective to initiate the graft polymerization of the monomers; and (iii) a reducing agent capable of reducing nickel ion to nickel metal. The composition and substrate are heated for a time and at a temperature effective to graft polymerize the monomers and nickel metal onto the substrate and form a conductive, tenacious, and protective coating bonded to the substrate. The coating can also contain elemental phosphorous. Preferably, the coated substrate has a surface resistivity of less than 0.1 ohm per square. The method, coated substrate, and composition are useful for improving the electro-magnetic compatibility (EMC) and electro-static discharge (ESD) protection of electrical enclosures.

    摘要： This invention relates to the coating of steel parts with organic polymeric materials for resistance to corrosion, abrasion, impact, salt solutions of high and low pH (both in liquid as well as vapor state) and corrosive atmospheric gases under the environment of high relative humidity and ambient conditions of temperature and pressure. To obtain secure and permanent adhesion of the coating on the steel article a polymeric coating is formulated so as to achieve chemical grafting to the steel face. This involves the use of monomers, prepolymers, catalyst and a graft initiator system. The monomers are preferably polyfunctional and when applied onto a metallic substrate, react via graft polymerization with the metal to form a polymerized layer coated onto the surface of the steel substrate. The monomers and prepolymers are so selected that when polymerized onto steel the coating has substantially zero moisture vapor-gas transmission rate and consequently acts as a barrier to moisture, oxygen and other gases from coming in contact with the surface of the steel substrate thereby improving the protective potential of the coating. Fillers may be included in the coating material to enhance physical or wear characteristics. Other components that can be added are slip agents, wetting agents, thixotropic promoters and adhesion promoters. This coating process is particularly advantageous for use with steel parts used in the manufacture of cranes

    摘要： The present invention relates to a polymeric coating composition for application onto glass substrates for anti-reflective properties. The coating is provided via chemical grafting that involves the use of monomers and/or prepolymers, catalyst, and graft initiator and when applied onto the surface of the glass substrate forms a polymeric film chemically bonded to the glass with excellent adhesion. This coating can reduce the reflectance of the coated glass surface to as close to zero as possible, thus maximizing transmittance and providing resistance to abrasion, water/chemical attack, and UV degradation.
