摘要： The invention relates to an electrochromic glass component, particularly for motor vehicle mirrors, which contains a doped ion-conducting basic polymer (4) as the ion-conducting layer. The electrochromic glass component consists, for example of a glass substrate (1) as well as a layer system having an electrochromic layer (2), a mirror layer (3), a doped polymer membrane (4), for example of polybenzimidazole polymer, a proton store (5), a rear electrode (6) and a polyester film (7). The layer system is sealed by a seal (8) which closes the coating system towards the glass substrate (1).

摘要： The invention relates to a method for producing aqueous, hydrous and non-aqueous solutions of polymers that are functionalized by acid groups. The method is characterized in that the heat needed to produce the solution is supplied by microwave radiation. These solutions can be used as a starting material for the production of gas diffusion electrodes, fuel cells and platinum nanoparticles stabilized by polymer-electrolytes.

摘要： The invention relates to soluble nanoparticles having a diameter of 0.5 to 3 nm, preferably of 1 to 2 nm, containing the platinum alone or platinum and other metals of the platinum group. The nanoparticles are embedded in a protective colloid containing polymeric betaine which can be degraded by hydrolysis. The betaine is preferably a carbobetaine of formula -N?+R1R2-(-CH¿2-)n-CO2-, a phosphobetaine of formula -N+R1R2-(-CH2-)n-PO3- or, preferably a sulfobetaine of formula -N+R1R2-(-CH2-)n-SO3-, whereby R?1 and R2¿, independent of one another, can be the same or different, and represent alkyl radicals of 1 to 6 carbon atoms, and n represents 1, 2, or 3.
