20140091031 | ANTIMICROBIAL MEMBRANES - The present invention discloses the preparation of antimicrobial membranes by inclusion of low leaching, control release silver-based antimicrobial additives as described in claim | 04-03-2014 |
20130255761 | ELECTRODE AND DYE-SENSITIZED SOLAR CELL - A working electrode and dye sensitized solar (DSSC) cell having working electrode where the working electrode includes a porous metal foil conductor and a particulate metal oxide layer on the side of the foil for facing incident light and process for preparing the electrode and | 10-03-2013 |
20130052277 | PROCESS FOR THE PREPARATION OF AN ANTIMICROBIAL ARTICLE - 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. | 02-28-2013 |
20130004454 | POLYURETHANE BLOCK COPOLYMER BASED ON POLY SILOXANE TENSIDE FOR MEMBRANES - Oligo- or polyurethane compounds of the formula (I) wherein k and n independently are numbers from 1 to 100, m is from the range 1-100, (X) is a block of formula (II) and (Y) is a block of the formula (III), (A) is a residue of an aliphatic or aromatic diisocyanate linker, (B) is a residue of a linear oligo- or polysiloxane containing alkanol end groups, and optionally further containing one or more aliphatic ether moieties, and (C) is an aromatic oligo- or polysulfone block, may advantageously be used as anti-adhesion additives in polymer compositions e.g. for membranes; related oligo- or polyurethanes wherein m is 0 are especially suitable for the preparation of antimicrobial water separation membranes. | 01-03-2013 |
20120177713 | NANO SILVER-ZINC OXIDE COMPOSITION - 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 50 μm 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. | 07-12-2012 |
