Thermotrope Materialien für den Einsatz in „intelligenten Fenstern" / Thermotropic materials for application in "intelligent windows"

Thermotropic materials as integrated part of „intelligent windows" based on polymer gel networks are developed. Systems change the transparency in dependence on temperature. These windows are able to protect buildings against superheating by sunshine. The aim of this work is the formation of a thermotropic material which operates like a heat filter. The effect is based on reproducible reversible phase transitions in the material. A decisive aspect is the adjustment of these transitions between the optical clear or opaque state of the windows, controled by the solar energy, to the perception of the human eye.
