Estimating the term…
The invention relates to multilayer systems for selective reflection of electromagnetic radiation from the wavelength spectrum of sunlight, and to a method for producing said systems on suitable, preferably polymeric, carrier materials. Such a multilayer system of the invention is formed with at least one layer composed of silver or silver alloy, which is coated over the whole area on both surfaces with in each case a seed layer and a cap layer. In this case, the seed layer and cap layer are formed from dielectric material. These are ZnO and/or ZnO:X. In this case, at least one such multilayer system is formed on a flexible polymeric substrate, preferable a film which is optically transparent in the visible spectral range.
A multilayer system for selective reflection of electromagnetic radiation from the wavelength spectrum of sunlight, comprising a flexible polymeric substrate, at least one a seed layer, at least one layer of silver or a silver alloy that is coated on the at least one seed layer, and at least one cap layer coated on the at least one seed layer, wherein the seed layer and cap layer are formed from a dielectric material comprising ZnO and/or a mixed zinc oxide, ZnO:X.
