    Abstract: A new composite comprises (a) 10.1 -99.9 % by weight of elemental Ag and (b) 0.1 -89.9 % by weight of ZnO, wherein the sum of (a) and (b) makes 90 % or more by weight of the composite and wherein the elemental Ag has a primary particle size of 10-200 nm and/or the ZnO has a primary particle size of 0.1 to below 50μm and/or the composite has a particle size distribution of 0.1 - 50 μm and/or a BET surface area of 10-100 m2/g. The novel composite may be obtained by the steps (i) mixing a first mixture of at least one Ag-salt with a second mixture of at least one Zn-salt thereby forming a third mixture of Ag- and Zn-salts, (ii) adding the third mixture to a mixture of a carbonate source, (iii) co-precipitating of the Ag- and Zn-carbonates formed in step (ii), (iv) washing of the Ag- and Zn-carbonates and (v) thermal decompositing of the Ag- and Zn-carbonates. The novel composites are useful to impart antimicrobial properties to surfaces, articles or bulk compositions, especially to membrane systems for gas- or water separation.

    Abstract: Disclosed is a process for preparing an antimicrobial article, wherein a silver colloid is formed in situ as a result of the components employed. The process comprises the steps of (i) providing a liquid, which contains a soluble polar polymer in a solvent selected from certain polar organic solvents; (ii) adding a silver salt selected from alpha-functionalized silver carboxylates to said liquid; (iii) allowing the mixture to react with formation of a silver colloid; and (iv) separating the solvent from the mixture and forming of the antimicrobial article. The antimicrobial articles thus obtained may be sheets, films, fibres, coating layers, and especially membranes like a semipermeable membrane for ultrafiltration, water separation or gas separation.

    Abstract: A method of controlling the degradation of a polymeric film to cause the film to degrade after an intended useful life time includes providing a polymeric film comprising a polymer and prodegradant for the polymer adapted to be activated on irradiation with a controlled dosage of electromagnetic radiation, activating one or more sources of artificial radiation adapted to emit electromagnetic radiation and irradiating at least part of the polymeric film with the artificial radiation. The electromagnetic radiation comprises wavelengths less than about 400 nm. A system for predisposing a polymeric film containing a prodegradant to degrade after an intended service life includes one or more sources of artificial radiation and an irradiation controller, together with a film dispenser dispensing film into the irradiation zone.
