Beschreibung
Zusammenfassung:	The functional layer (3) of an element for controlling the temperature of a surface consists of an IR-transparent matrix material with embedded microparticles (4) made of a material having a semiconductor/metal phase transition. An element for controlling the temperature of a surface comprises: a substrate (1); an IR-reflecting layer (2); and a functional layer (3) that can be switched between an IR-absorptive state and an IR-transparent state. The functional layer consists of an IR-transparent matrix material with embedded microparticles (4) made of a material having a semiconductor/metal phase transition. An Independent claim is also included for a process for stabilizing the operating temperature of a surface to a predetermined value by the self-regulating release of heat radiation comprising applying an element as above to the surface. Die Erfindung betrifft ein Element zur Steuerung der Temperatur einer Oberfläche. Es weist folgenden Schichtaufbau auf: DOLLAR A - Substrat (1), DOLLAR A - IR-Reflektorschicht (2), DOLLAR A - Funktionsschicht (3), die zwischen einem IR-absorptiven Zustand und einem IR-transparenten Zustand umschaltbar ist. DOLLAR A Dabei besteht die Funktionsschicht (3) aus einem IR-transparenten Matrixmaterial, in das Mikropartikel (4) aus einem Material, das einen Halbleiter/Metall-Phasenübergang aufweist, eingelagert sind.
